Test the claim about the difference between two population means , and 2 at the level of significance o. Assume the samples are random and independent, and the populations are normally distributed. Claim: H1 = H2; a = 0.01. Assume of = 03 Sample statistics: X1 = 31.5, s, = 3.3, n1 = 14 and X2 = 34.2, $2 = 2.3, n2 = 15 . . . . . Identify the null and alternative hypotheses. Choose the correct answer below. OA. HO: M1 # H2 OB. HO: H1 > H2 Ha: 1 = H2 Ha: H1 S H2 O C. HO: My SH2 OD. HO: H1

H2 Ha: H1 2 H2 OE. HO: M1 = H2 OF. HO: M1 2 H2 Ha : H1 # H2 Ha: H1
