WebAdministration is considering taking more samples like this. Suppose that of all 500 500 employees of the organization, it's actually 10\% 10% that are allergic. Let \hat p p^ represent the proportion of a sample of 35 35 employees that are allergic to pets. What are the mean and standard deviation of the sampling distribution of \hat p p^? Web2 7 Example: Sampling Distribution for a Sample Proportion • Suppose (unknown to us) 40% of a population carry the gene for a disease (p = 0.40). • We will take a random sample of 25 people from this population and count X = number with gene. • Although we expect to find 40% (10 people) with the gene on average, we know the number will vary for different …

WebDescribe the sampling distribution of p^. Assume the size of the population is 30,000 . n = 700,p = 0.791 Describe the shape of the sampling distribution of p^. Choose the correct answer below. A. The shape of the sampling distribution of p^ is not normal because n ≤ 0.05 N and np(1−p) ≥ 10. B. WebMay 18, 2024 · The sampling distribution of p hat is approximately Normal because n p = 17.4 greater-than 10. Because n (1 minus p) = 20 (1 minus 0.87) = 2.6 less-than 10, the sampling distribution of p hat is not approximately Normal. The sampling distribution of p hat is skewed right and centered at 0.87. rc tank stand
