Q1.  Assume that weights of men are normally distributed with a mean of 172 lb and a
standard deviation of 29 lb.
Use a Table A-2 and TI 84 to find the answer of each part. Draw a density curve for each.
a) Find the weights that separated the bottom 5% and the top 5% of the men.
b) Find the weights that separated the bottom 70% from the top 30% of the men.
c) Find the probability that if an individual man is randomly selected, his weight will be
greater than 200 lb. Find the z score for 200 lb.
d) Find the probability that 49 randomly selected men will have a mean weight that is less
than 175 lb. Find the z score for 175 lb.
