To test the Ho: u = 60 versus Hi: u < 60, a random sample of size n = 23 is obtained from a population that is known to be normally distributed.  Complete (a) through (d).

if x = 56.1 and s = 13.6, compute the test statistic.

to = ??? (round to three decimals 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 sued to find critical value, in this problem use the t-distribution table given.

c) Draw a t-distribution that depicts the critical region.  

d) Will the researcher reject the null hypothesis?

No because the test statistic does not fall in the critical region

Yes because the test statistic does not fall in the critical region

Yes because the test statistic falls in the critical region

No because the test statistic  fall in the critical region
