In order to ensure efficient usage of a server, it is necessary to estimate the mean number
of concurrent users. according to records, the average number of concurrent users at 100
randomly selected times is 37.7, with a standard deviation ? = 9.2.
(a) construct a 90% confidence interval for the expectation of the number of concurrent
users.
(b) at the 1% significance level, do these data provide significant evidence that the mean
number of concurrent users is greater than 35?
