Technology and the Internet Intel and Test Devices recently began shipping a smart baby body suit called Mimo.39 This baby onesie has an Internet connection that allows parents to monitor an infant at all times. A random sample of infants (less than 1 year old) was obtained, and each was fitted with a Mimo. The suit was used to monitor sleeping respiratory rates (breaths per minute), and each child was classified by position: on the back or on the stomach. The data are given in the following table.

Is there any evidence to suggest that the respiratory rates are different for these two sleeping positions? Assume that the underlying distributions are continuous and use a Wilcoxon rank-sum test with a = 0.01.
