Question 3. Suppose you draw random samples of size n=25 from N(µ, o²). Construct a 99% confidence interval estimate for the population average, u, using the following sample information, 25 Xị = 10113.8 i=1 25 x? = 4,232,017 With variance unknown, you should use the t-distribution for the sampling distribution of the sample mean.
