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.
