Managing Ashland MultiComm Services
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.
Continuing its monitoring of the upload speed first de-
scribed in the Chapter 6 Managing Ashland MultiComm
Services case on page 221, the technical operations depart-
ment 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
