It is known that the mean cholesterol level for all the people is 190, and the
standard deviation is 15. We test 100 random smokers! and find that the average
cholesterol level in our sample is 195. Can we claim based on that sample that the
cholesterol level of smokers is higher than that of the general population, if we
need the confidence level a=0.99 to make our claim (use Hypothesis Testing to
answer this question)? (20 points).
