Test the claim about the population mean, mu , at the given level of significance using the given sample statistics.

Claim: p =50; alpha = 0.09, sigma = 3.58. Sample statistics : x_bar = 49.3, n = 61

Identify the null and alternative hypotheses. Choose the correct answer below.

A. Ho: u<50> Ha: u=50

C. Ho u=50

Ha: u<50>

E. Ho: u > 50

Ha: p=50

B. Ho: != 50

Ha: p=50

D. Ho: u = 50

Ha:p> 50

F. Ho: u = 50

Ha: u # 50
