Question

A survey in 2009 asked 125 college students how many text messages they send in a day. One histogram shows the distribution of the number of texts sent for all respondents. The other three graphs show distributions of sample means for random samples taken from the population of students. One histogram shows sample means based on samples of size n = 5 students; another shows sample means based on samples of n = 10 students; and another shows sample means based on a sample of n = 25 students.

- Sampling distribution of ¯yy¯, n = 10

- Sampling distribution of ¯yy¯, n = 25

- Population

- Sampling distribution of ¯yy¯, n = 5

Explanation / Answer

sample mean with large sample size will have less variability as compared to population.

somce Graph A has highest variability followed by

Graph A: Population

Graph B: sampling distribution with n=25

Graph C: sampling distribution with n=5

Graph D:sampling distribution with n=10
