You are testing the following null and alternative hypotheses using (120.05 : Hozp:D;Ha:u

You are testing the following null and alternative hypotheses using a=O.05 Suppose 0=20, and x=-6. Calculate the test statistic and the p -value for n=18, 38, 58, 78, and 98. Give the test statistic to two decimal places and the p -value to four decimal places. n n n = 18: =38 : = 58 : and and and and and P P P P P This suggests that, as sample size increases, O There is no effect on significance. O A test becomes less significant. O A test becomes more significant.
