Question: Random samples of sizes n1 = 16 and n2 = 12 were drawn from populations 1 and 2, respectively. The measurements obtained are listed in

Random samples of sizes n1 = 16 and n2 = 12 were drawn from populations 1 and 2, respectively. The measurements obtained are listed in the next table (p. 14-16) and saved in the LM14_22 file.

a. Conduct a hypothesis test to determine whether the probability distribution for population 2 is shifted to the left of the probability distribution for population 1. Use a = .05.
b. What is the approximate p -value of the test of part a ?
