An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 120 lb and 181 lb. The new population of pilots has normally distributed weights with a mean of 128 lb and a standard deviation of 32.4 lb.
a. If a pilot is randomly selected, find the probability that his weight is between 120 lb and 181 lb.
The probability is approximately __. (Round to four decimal places as needed.)
b. If 32 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 181 lb.
The probability is approximately __. (Round to four decimal places as needed.
c. When redesigning the ejection seat, which probability is more relevant?
A. because the seat performance for a single pilot is more important.
B. because the seat performance for a single pilot is more important.
C. because the seat performance for a sample of pilots is more important.
D. because the seat performance for a sample of pilots is more important.

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs opens on day 1 with 6000 shares at $4.60 per share. the price of stock abc on day 8 begins at $3.50. the price of stock xyz on day 8 begins at $3.90. stock qrs opens on day 8 with a price of $4.50 per share. assume that each stock has the same number of shares that it opened with on day 1. what is the rate of change of this simple index over 1 week?
