The response time of a distributed computer system is an important quality characteristic. From previous experience, it is known that the standard deviation of response time is 6.0 milliseconds and the sample average response time is 50.0 milliseconds.
Assuming the response time follows a normal distribution, what is the probability that the response time is more than 57 milliseconds?
Answer tolerance: +/- 0.03

The response time of a distributed computer system is an
important quality characteristic. The system manager wants to know
whether the mean response time to a specific type of command
exceeds 82 millisec. The computer systems are known to have a mean
response time of 84.25 millisec and standard deviation of 10
millisec. The command is executed 25 times.
Test the hypothesis that the mean response time is 82 millisec
versus the alternative that the mean exceeds 82 millisec. Use...

Suppose that from previous experience, you know that given
investment is normally distributed, has a mean return of 12%, and
there is an 82% chance that the investment’s return is less than
(or equal to) 16%. What is the standard deviation of the
investment’s return?

An important quality characteristic used by the manufacturers of
ABC asphalt shingles is the amount of moisture the shingles contain
when they are packaged. Customers may feel that they have purchased
a product lacking in quality if they find moisture and wet shingles
inside the packaging. In some cases, excessive moisture
can cause the granules attached to the shingles for texture and
colouring purposes to fall off the shingles resulting in appearance
problems. To monitor the amount of moisture present,...
