EBook Problems Set - Estimating a Population Variance

Problem 1

We have discussed that the standard deviation of the distribution of sample percentages or SE(p hat) is calculated by taking the square root of

p hat * (1 - p hat)/ N , where p hat is the proportion in the sample and N is sample size

What does SE(p hat) show?

  • Choose one answer.
(a) It shows the standard error of the man across repeated samples from the population.
(b) It shows the distribution of p hat for the single sample that the researcher draws from the population.
(c) It shows the standard deviation of p hat for repeated samples from the population.
(d) It shows the variation for p hat values for repeated samples from the population.
