1. referring to the results of Problems 9.76 through 9.78 concerning Boston and Vermont shingles, write a report that evaluates the moisture level, weight, and granule loss of the two types of shingles.

2. Continuing its monitoring of the upload speed first described in the Chapter 6 Managing Ashland MultiComm Services case on page 243, the technical operations department wants to ensure that the mean target upload speed for all Internet service subscribers is at least 0.97 on a standard scale in which the target value is 1.0. Each day, upload speed was measured 50 times, with the following results (stored in AmS9).

0.854 1.023 1.005 1.030 1.219 0.977 1.044 0.778 1.122 1.114 1.091 1.086 1.141 0.931 0.723 0.934 1.060 1.047 0.800 0.889 1.012 0.695 0.869 0.734 1.131 0.993 0.762 0.814 1.108 0.805 1.223 1.024 0.884 0.799 0.870 0.898 0.621 0.818 1.113 1.286 1.052 0.678 1.162 0.808 1.012 0.859 0.951 1.112 1.003 0.972

1. Compute the sample statistics and determine whether there is evidence that the population mean upload speed is less than 0.97.

2. Write a memo to management that summarizes your conclusions.
