O POInts:Oof2 To test Ho: 60 versus HI : < 60, a random sample of size n = 26 is obtained from a population that is known to be normally distributed Complete parts (a) through (d) below Click here to view the t-Distribution Area in Right Tail: (a) If 57 A and s = 12@ compute the test statistic. to = 1.1558 (Round to three decimal places as needed) (b) If the researcher decides to test this hypothesis at the 0 05 level of significance. determine the critical value(s). Although technology or a t-distribution table can be used to find the critical value, in this problem use the t-distribution table given. Critical Value: o M29 (Round to three decimal places. Use a comma to separate answers as needed)
