@whuber is correct. Your tabulation yields: This treats the counts (1, 4, 8, 13) as fixed levels of a categorical variable. It seems you want to test if the counts are approximately equal. If we take the sum (26) as the total, out of which, say, 13 became c's, you can test your observed counts against a discrete uniform distribution, which is what would occur if each instance had an equal chance of becoming each sampleID. This is a one-way chi-squared test; it is also called a goodness of fit chi-squared test, as you are testing the fit of your data to the discrete uniform. In R, that would be: On the other hand, perhaps you had one subject in each condition and counted how many times that person did something. In this case, the conditions are fixed a-priori and the counts are the outcome (the opposite of before). You would need multiple participants to get a measure of variability, but if you assume the Poisson distribution (see my answer here: Help me understand poisson.test?), you could conduct fit a model, since the Poisson has a fixed dispersion. In R, this would be: From there, you can use the null and residual deviances to conduct a test (see my answer here: Test GLM model using null and model deviances). In R, you would do: Under either interpretation, your results are significant by conventional criteria

How do I get free makeup samples without filling out surveys...and dealing with the scams?

What is the distribution of the number of occurrences of a given integer, in repeated samples drawn from Uniform Integer [1, N] distribution?

In a single draw, your chosen integer will be drawn with probability $\frac{1}{N}$. Since you draw with replacement, the total number of such successes is binomially distributed with parameters $M$ and $p=\frac{1}{N}$

How do I effectively visualize data showing change in a lot of samples over two time periods? [closed]

One solution is to plot exactly the data you are trying to describe - the delta in your values.Consider a bar-plot (with confidence/error bars) showing the plant number along the x-axis and the y-axis showing the change in count with +ve and -ve values. For example, using the data from your question, this visualisation shows clearly that all values bar one decreased from 2015 to 2016 (please forgive the crude diagram lacking titles etc): Of course it would also be helpful to show a graph of the absolute values and it is obligatory to include a table of the exact values too.

When you are pregnant do you have to do blood samples?

oh yeah... lots of blood giving... :-) but it is all worth it in the end

How do I know whether future samples will remain below a threshold?

You want to assess whether the probability $\Pr(X>1)$ is significantly higher than $99\%$.To do so, you can derive a confidence interval about $\Pr(X>1)$. For example you can get such a confidence interval using the Bayesian approach with the Jeffreys prior. Another way is to use a lower tolerance limit. If the lower $(1-\alpha, p=99\%)$-tolerance limit is higher than $1$, then the probability $\Pr(X>1)$ is significantly higher than $99\%$ at the $\alpha$-level of significance.Example:The lower tolerance limit is $\approx 1. 35 > 1$, then $\Pr(X>1)$ is significantly higher than $99\%$ at the significance level $\alpha=5\%$.Using the Jeffreys Bayesian approach:The lower $95\%$-confidence bound of $\Pr(X>1)$ is $\approx 99.5\%$, then $\Pr(X>1)$ is significantly higher than $99\%$ at the significance level $\alpha=5\%$. If you do not like the Jeffreys approach, you can use these approximate confidence bounds of $\Pr(X>q)$:sources: The lower bound is similar to the previous one:

  • Street Lights of Led Monitor

    EESL provides a service to enable municipalities to replace conventional street lights with LEDs at no upfront cost. The cost difference is paid back through the municipalities through energy savings. The Street Lighting National Programme (SLNP) aims to replace 3.5 crore conventional street lights with smart and energy efficient LED street lights by March, 2019.

    For the programme, the total connected load of street lights across the country of around 3400 MW, can be reduced to 1400 MW, saving 9 billion KWh and Rs. 5,500 crore to municipalities annually. Use of LEDs in public lighting can save more than 50% of energy consumption.

    A total of 19.6 lakh LED street lights were already replaced, saving 7.5 lakh kWh per day, avoid capacity of 68.5 MW and reducing 627 t of CO2.

Power calculation of Outdoor Solar Street lights
Power calculation of Outdoor Solar Street lights
Outdoor solar street light designOutdoor solar street lights are composed of solar panels (including brackets), lamp holders, control boxes (with controllers and batteries, etc.), and light pole foundations. Solar street lights are generally separate power supply systems and are not connected to the power supply network of conventional street lights. There are three main types of solar street light systems: 12V, 3.2V, and 3.7V.Solar street light battery selection1. Type of outdoor solar street light battery Solar cells convert solar energy into electricity. There are two more practical ones, such as monocrystalline silicon and polycrystalline silicon. 1) The performance parameters of monocrystalline silicon solar batteries are relatively stable, suitable for use in places where the average sunshine time exceeds 4 hours; 2) Polysilicon solar panels are suitable for use in places where the sunshine time is less than 4 hours;2. Working voltage of the outdoor solar street light battery The working voltage of the solar street light battery is about 1.5 times of the battery voltage to ensure the normal charging of the lithium battery. For example, 5V~6V is needed to charge the 3.2 battery.Solar street light battery requires 15-18V solar battery to charge 12V lithium battery. To charge the 24V lithium battery, a 33~36V solar battery is required.   The following mainly introduces the relationship between the power of the light source, the voltage capacity of the lithium battery, and the volt power of the solar street light panel.W (energy) = P (power) × T (time)According to the law of conservation of energy, the solar panel converts light energy into electrical energy through photoelectric conversion and is stored in a lithium battery. The electrical energy in the lithium battery is converted into light energy to provide energy to the LED at night. The three have a common unit called watts. When Wh, 1Wh=1W × 1h, for example, the energy consumed by a 1W light for one hour is 1Wh. There is another word in physics that means energy, called Joule J, 1J = 1W × 1S (seconds), for example, A 1W heating wire generates 1J in 1 second, so 1Wh = 1J × 3600s = 3600J. Both actually represent energy. The difference is that Joule is generally used to represent heat energy, such as the very classic Joule's law in physics. (Joule's law is the law that quantitatively states that conduction current converts electrical energy into heat. The content is: the heat generated by the current passing through the conductor is proportional to the square of the current, proportional to the resistance of the conductor, and proportional to the time it takes to energize.Why LED lights generate heat is actually because part of the electrical energy is converted into heat energy. The greater the current, the greater the heat generation, and the greater the resistance, the greater the heat generation. Therefore, the high-power LED lights of the mains must be designed for heat dissipation. Solar energy Why do we say that the thickness of the copper wire is important? It is also closely related to this Joule's law. )W=U (Lithium battery voltage) × C (Lithium battery capacity)C (Lithium battery capacity) = I (current) × h (time)W=U (lithium battery voltage) × I (current) × h (time) = P (power) ÷ h (time)The maximum charging current of the solar panel is I (current) = P (solar panel power) ÷ U (solar panel voltage)We take the average sunshine time as the working time of the solar panel, and the capacity that the solar panel can charge the battery in a day is: C (capacity) = I (current) × h (average sunshine time) = P (solar panel power) ÷ U (Solar panel voltage) × h (average sunshine time)The energy-charged into the lithium battery is: W = U (lithium battery voltage) × C (capacity)Theoretically, the energy used by the lamp holder in a day cannot exceed the energy of the solar panel to charge the lithium battery in a day, otherwise the solar lamp will not be able to light up all night.
