Based on the sample proportion you obtained. We will turn to an applet called “Simulating Confidence Intervals” to illustrate how to interpret a confidence level. First make sure that the method is set to “Proportions” and “Wald.” Set the population proportion to be .45, the sample size to be 75, and the confidence level to be 95%.

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 ...
