Answer:
The basic procedure is:
State the null hypothesis H0 and the alternative hypothesis HA.

Calculate the test statistic: z = p ^ − p o p 0 ( 1 − p 0 ) n.
Calculate the p-value.
Make a decision. Check whether to reject the null hypothesis by comparing p-value to

Answer:
Based on procedures A and B, the glaciers have lost thickness and have retreated in recent years.
Explanation:
The long-term "benchmark" glacier program managed by the U.S. Geological Survey monitors climate, glacier geometry, glacier thickness, glacier motion, and stream runoff (procedure A) in the ways to understand the consequences of climate change through monitoring the balance between accumulation and melting, which results in the change in glacial thickness of ice over the 40 year record from 1965 to 2005.
The Taku and Norris Glaciers as well as land contours and the positions of the edge of each glacier at different times since 1890 (procedure B) show that glaciers gain and lose snow and ice each year, and this causes the glacier
to advance but when the snow and ice melt, the glacier retreats and moves up the hill.
