A metropolitan children's museum open year-round wants to see if
the variance in daily attendance differs between the winter and
summer months. Random samples of 25 summer days and 31 winter days
were selected and showed that in the summer months, the sample mean
daily attendance was 280 with a standard deviation of 65, and the
sample mean daily attendance for the winter months was 300 with a
standard deviation of 52.
a.) Assuming the attendance is normally distributed, construct a
90% confidence interval for ??^2/??^2, the true ratio of the
variances during the summer and winter months. Round your final
answer to 3 decimal places.

The university data center has two main computers. The center wants to examine whether computer 1 is receiving tasks that require processing times comparable to those of computer 2. A random sample of 9 processing times from computer I showed a mean of 52 seconds with a standard deviation of 19 seconds, while a random sample of 14 processing times from computer 2 (chosen independently of those for computer 1) showed a mean of 56 seconds with a standard deviation...

A light bulb manufacturer wants to compare the mean lifetimes of two of its light bulbs, model A and model B. Independent random samples of the two models were taken. Analysis of 11 bulbs of model A showed a mean lifetime of 1345 hours and a standard deviation of 102 hours. Analysis of 15 bulbs of model B showed a mean lifetime of 1389 hours and a standard deviation of 82 hours. Assume that the populations of lifetimes for each...

00 Pilots who cannot maintain regular sleep hours due to their work schedule often suffer from insomnia. A recent study on sleeping patterns of pilots focused on quantifying deviations from regular sleep hours. A random sample of 15 commercial airline pilots was interviewed, and the pilots in the sample reported the time at which they went to sleep on their most recent working day. The study gave the sample mean and standard deviation of the times reported by plots, with...
