Let
be the mean of
. Then
For a random variable
following the standard normal distribution, we have
Transform the random variable to get this critical value in terms of
:
Answer: 
Step-by-step explanation:
Given : Significance level : 
Sample size : n=85
Critical value : 
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :-
Thus, the 95% confidence interval for the true mean cholesterol content, μ, of all such eggs =
Hence, we conclude that the true population mean of amount of cholesterol lies between 182.356 and 197.644.
Given:
Jason buys three shirts with a listed price of $20 each.
He uses a coupon that provides "Buy Two, Get One Free".
To find:
The total final price Jason pays.
Solution:
Total number of shirts he buys = 3
