construct 90, 95, and 99 percent confidence intervals for the
population mean, and state the practical and probabilistic
interpretations of each. Indicate which interpretation you think
would be more appropriate to use. Explain why the three intervals
that you construct are not of equal width. Indicate which of the
three intervals you would prefer to use as an estimate of the
population mean, and state the reason for your choice.

PROBLEM 5. 20 Construct the 95 percent Confidence intervals for
the following cases, state any needed assumptions, and give
interpretation
n1 = 9 X1 bar = 75 sigma1 = 5, n2=9 X2 bar = 70 sigma2 = 3
Among 100 females 60 like Sports, Among 50 males 40 like
sports
Find Confidence interval for p1 – p2, where p1 is true proportion
of women that like sports.
