A sample of 45 pro football players had an average height of 6.179ft with a sample standard deviation of 0.366ft and a sample of 40 pro basketball players had a mean height of 6.453ft with a sample standard deviation of 0.314ft. If mu1 is the mean height for all football players and mu2 is the mean height of all basketball players, find a 90% confidence interval for mu1 - mu2. Interpret the confidence interval in the context of the problem.

The population standard deviation for the height of college
football players is 3.3 inches. If we want to estimate a 90%
confidence interval for the population mean height of these players
with a 0.7 margin of error, how many randomly selected players must
be surveyed? (Round up your answer to nearest whole number)

The average height of 12 randomly selected Muppet basketball
players is 50 inches with a standard deviation of 4 inches. The
average height of 15 randomly selected Muppet football players is
47 inches with a standard deviation of 3 inches. Assuming the
heights of both populations are normally distributed, are Muppet
basketball players taller than football players?

basketball players’ vertical jumps is 10 inches.
a. Determine a 95% confidence interval for the average
vertical jump and determine the margin of error.
b. Interpret your result.
c. If you want a margin of error of only 1 inch in the 95%
confidence interval, determine the number of basketball players you
would need to sample. show all work
