(a) If x = 37.1 ands= 10.3, compute the test statistic.
tn = - 1.379 (Round to three decimal places as needed.)
(b) If the researcher decides to test this hypothesis at the a= 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:
