Sample Proportion Example, org/math/ap-st Jul 15, 2025 · In this example, you are comparing the probability of being married between females and males. Suppose that 2/3 of all males wash their hands after using a public restroom. Use the Standard Deviation Calculator if you have raw data only. 6 mean = 1 stddev = 1 ntotal = 10 power = . It is denoted as p̂ (p-hat) and is calculated by dividing the number of successes in the sample by the total number of observations in that sample. The sampling distribution of ^p is the probability distribution of all the possible values of ^p. We can describe the sampling distribution with a mathematical model that has these same features. Since p was obtained through a random process, it is a random variable. We say that the proportion of the sample that belongs to this group is p = m=n. d.
