Question:

Consider the graph of the normal in Figure 5.12, which gives relative frequencies in a of men's heights. The has a mean of 69.6 inches and a standard deviation of 2.8 inches.
a. What is the total area under the curve?
b. Estimate (using area) the relative frequency of values less than 67.
c. Estimate the relative frequency of values greater than 67.
d. Estimate the relative frequency of values between 67 and 70.
e. Estimate the relative frequency of values greater than 70.

Consider the graph of the normal distribution in Figure 5.12,
