Here are summary data from a z test regarding scores on the Consideration of Future Consequences scale

Here are summary data from a z test regarding scores on the Consideration of Future Consequences scale (Petrocelli, 2003): the population mean (μ) is 3.51 and the population standard deviation (σ) is 0.61. Imagine that a sample of 45 students had a mean of 3.7.

 

a. Calculate the test statistic for a sample of 5 students.

b. Calculate the test statistic for a sample of 1000students.

c. Calculate the test statistic for a sample of 1,000,000 students.

d. Explain why the test statistic varies so much even though the population mean, population standard deviation, and sample mean do not change.

e. Why might sample size pose a problem for hy - pothesis testing and the conclusions we are able to draw?
