Please correctly state H0 and Ha. The options for the claim is the ___hypothesis is either “null” or “alternative” Part D options are) First part “reject” or “fail to reject” and the last part is “is” or “is not” Part E) First part “is” or “is not”, second part “support” or “reject”, and the last part’s options are “Less than equal”, “less than”, “equal”, “not equal”, “greater than or equal”, and “greater than”
(c) Find the standardized test statistic, t.
The standardized test statistic is t=
