Perform a two-sample hypothesis test to consider if the yields for product A and product B are different.

significance level of α=0.05.

You may assume that the population variances for product A and B are equal.

You should take the mean of Yield A first in the calculation of your test statistic.

(a) State the null hypothesis and the alternate hypothesis.

(b) Calculate the test statistic, taking note of the order of calculation as indicated in the question t= ______

(C) State the Degrees of Freedom, df = _______

(d) Look up the upper tail critical value from tables (state to 3dp as given in tables) tc = __________

(e) What is your decision regarding H0 ?
