For the two measurement problem, use an a = 0.05 level of significance. Conduct
appropriate hypothesis tests and conclude whether to reject or not reject the claim that:
a. there is no difference in population mean satisfaction depending on time of
contact,
b. there is no difference in population mean satisfaction depending on type of
customer contact and
c. there is no interaction between type of contact and time of contact.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8c05791e-96fa-4be9-8e2f-e7c1502f15bd%2F8866470d-6e2f-4508-84f0-bcb2a1f851ff%2Fr7g1p4_processed.png&w=3840&q=75)
