You are testing the null hypothesis that = 0 versus the alternative > 0 using = 0 .05. Assume that = 16. Suppose that x = 8 and n = 10. Calculate the test statistic and its p-value. Repeat assuming the same value of x but wtih n = 20. Do the same for sample sizes of 30, 40, and 50. Do the same for the p-values. Summarize what this demonstration shows about the effect of the sample size on significance testing.
