To test HO:u=100 versus H1 not equal to 100, a simple random sample of n=21 is obtained from a population that is known to be normally distributed. A if xbar =104 and s=9.5 the test statistic= 1.925 B. If the researcher decides to test this hypothesis at the a=.01 level of significance, determine the critical value(s). will there be more than one value? How do i solve this?
