To test Ho: μ = 40 versus H₁: μ<40, a random sample of size n = 24 is obtained from a population that is known to be
normally distributed. Complete parts (a) through (d) below.

.....
(a) If x=37.3 and s = 11.6, compute the test statistic.
to = -1.140 (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:
(Round to three decimal places. Use a comma to separate answers as needed.)
