€œBecause regional-scale atmospheric deposition data in the Rocky Mountains are sparse, a program was designed by the U.S. Geological Survey to more thoroughly determine the quality of precipitation and to identify sources of atmospherically deposited pollution in a network of high-elevation sites. Depth-integrated samples of seasonal snow packs at 52 sampling sites, in a network from New Mexico to Montana, were collected and analyzed each year since 1993.€ One of a number of chemical characteristics sampled was hydrogen. Following are the 5-year average results from each of the 52 sites.

a. Construct a stem-and-leaf plot of the data.
b. Describe the pattern you see in the stem-and-leaf plot.
c. Using the stem-and-leaf plot and the sign test, find the 95% confidence interval for the population median.
