For any sample size, the sample count X is binomial. When sample size is small, it is convenient to find the probability distribution of X using binompdf on your calculator. (X takes integer values from 0 to n.) Sample proportion. For any sample size, the sample proportion is not binomial but it is closely related since = X / n.

Now in this situation, the P-value is the probability of getting a sample proportion less than or equal to the one obtained in the sample if the null hypothesis is true. Since the significance level is the cut-off value for the P-value, the null hypothesis will be rejected if the P-value is less than the significance level.

The power is a probability and it is defined to be the probability of rejecting the null hypothesis when the alternative hypothesis is true. After plugging in the required information, a researcher can get a function that describes the relationship between statistical power and sample size and the researcher can decide which power level they ...
