Use technology and a t-test to test the claim about the population mean mu at the given level of significance alpha using the given sample statistics. Assume the population is normally distributed.
Claim: mu >71;alpha =0.01, Sample statistics: ar{x} =73.5,s=3.7,n=28

A.
H_(0):mu !=71
H_(4):mu =71
B.
H_(0):mu >=71
H_(A):mu <71
c.
H_(0):mu <=71
H_(A):mu >71
D.
H_(0):mu =71
H_(A):mu !=71
