MANAGING ASHLAND MULTI-COMM SERVICES
The AMS technical services department has embarked on a qualityimprovement effort. It’s first project relates to maintaining thetarget upload speed for its Internet service subscribers. Uploadspeeds are measured on a standard scale in which the target valueis 1.0. Data collected over the past year indicate that the uploadspeed is approximately normally distributed, with a mean of 1.005and a standard deviation of 0.10. Each day, one upload speed ismeasured. The upload speed is considered acceptable if themeasurement on the standard scale is between 0.95 and 1.05
1. Assuming that the distribution has not changed from what itwas in the past year, what is the probability that the upload speedat any time is:
a. Less than 1.0?
b. Between 0.95 and 1.0?
c. Between 1.0 and 1.05?
d. Less than 0.95 or greater than 1.05?
2. The objective of the operations team is to reduce theprobability that the upload speed is below 1.0. Should the teamfocus on process improvement that increases the mean upload speedto 1.05, or on process improvement that reduces the standarddeviation of the upload speed to 0.75? Explain.
