need this question answered as clearly as possibe, thank you so much, will give 5 stars if answer is correct.

Suppose the competing hypotheses for a test are H0 : p1 = #2 versus Ha : p1 7E p2. A 95% condence interval for the mean difference (#1 1:2) is calculated to be (-4.3, 1.9). At the 5% signicance level, the correct conclusion to the hypothesis test is Q a. Do not reject H0. we can't prove the means are different C) b. Reject H0, the means are the same 0 c. We do not have enough information to make any conclusion 0 d. Reject H0, the means are not the same 0 e. Do not reject HO, the means are not the same
