You are testing the null hypothesis that ? = 0 versus the alternative ? > 0 using ? = 0.05. Assume that ? = 16. Suppose that x = 8 and n = 20. Calculate the test statistic and its P-value. Repeat assuming the same value of x but with n = 30. Do the same for sample sizes of 40, 50, and 60. (Round the test statistic to two decimal places. Round the P-value to four decimal places.)
n = 20 z = ____________ P-value=__________________
n = 30 z = _____________ P-value = _________________
n = 40 z =_____________ P-value = ________________
n = 50z =_____________ P-value = _______________
n = 60 z =_____________ P-value = _________________
