To test H0:μ=100 vers H1:μ≠100, a simple random sample of size n=21 is obtained from a population that is known to be normally distributed. Answer parts (a)-(e). Click here to view the t-Distribution Area in Right Tail. Part 1 (a) If x=104.5 and s=9.7, compute the test statistic. t= (Round to three decimal places asneeded.) Part 2 (b) If the researcher decides to test this hypothesis at the α=0.01 level of significance, determine the critical values. (e a comma to separate answers as needed. Round to three decimal places as needed.) ( c ) Graph the T distribution (d) Will the researcher reject the nullhypothesis? (e) Construct a 99% confidence interval to test the hypothesis.
