If the alternate hypothesis states that mu > 6, 700, what is the rejection regio

Question

If the alternate hypothesis states that mu > 6, 700, what is the rejection region for the hypothesis test? A) Both tails B) Lower tail C) Upper tail D) Center portion of the curve E) None of the above Use the following to answer questions 15 to 18: A national manufacturer of ball bearings is experimenting with two different processes for producing precision ball bearings. It is important that the diameters be as close as possible to an industry standard. The output from each process is sampled and the average error from the industry standard is calculated. The results from two populations are presented below The researcher is interested in determining whether there is evidence that the two processes yield different average errors. Assume that the population standard deviations are equal. What is the alternate hypothesis? A) mu_A = mu_B. B)mu_A notequalto mu_B. C) mu_A lessthanorequalto mu_B. D) mu_A > mu_B. E) mu_A

Explanation / Answer

14) upper tail

15)option B is correct

16)

hence degree of freedom v=n1+n2-2 =12+14-2=24

option C

17) for 23 degree of freedom at 1% level of significance critical value of t=+/-2.797

option D

S1 0.0001 S2 0.00012 n1 12 n2 14 X1 0.002 X2 0.0026
