A statistics professor conducted a test of Ho: = 75 vs. Pla: < 75 for the mean of some normally distributed population. Based on the gathered data the statistician calculates the sample mean to be 72 and concludes that we reject Ho at the 10% level of significance. Using the same data, which of the following must be true? A test of Ho: = 75 vs. Ha: < 75 at the 5% level of significance would also lead to reject Ho. A test of Ho: = 79 vs. Ha: < 79 at the 10% level of significance WOU\d also lead to reject Ho. test of Ho: = 75 vs. Ha: 75 at the 10% level of significance would also lead Ill. to reject Ho.
