Data were collected from three populations- A, B, and C, -by means of a completely randomized design. The following describes the sample data:

nA = nB = nC = 15

RA = 235 RB = 439 RC = 361

a. Specify the null and alternative hypotheses that should be used in conducting a test of hypothesis to determine whether the probability distributions of populations A, B, and C differ in location.

b. Conduct the test of part a. Use a = .05.

c. What is the approximate p -value of the test of part b?
