Question
Use a t-test to test the claim about the population mean u at the given level of significance a using the given sample statistics. Assume the population is normally distributed.
Claim: µ2 8200; a = 0.01 Sample statistics: x= 7900, s =420, n= 22
What are the null and altenative hypotheses?
O A. Ho: us 8200
H,: p> 8200
O B. Ho: u28200
H u< 8200
Oc. Ho: u#8200
Hp= 8200
O D. Ho: µ = 8200
H p#8200
