Two-sample Non-parametric Test

Now, we examine the relationship between cry time and group among infants at Northbay.

1. Suppose we wish to perform a two-sample test, but we do not want to make any normality (or other strong parametric) assumptions. Conduct an appropriate non-parametric test to test whether the distribution of cry time is the same in both groups at the 0.05 level of significance.

What is your p-value?

unanswered

Your conclusion from the test?
there is evidence that the *means* of the two groups are different (specifically, there is evidence that the mean is higher in the control group) there is not evidence that the *means* of the two groups are different none of the above
