Acompany sells name plates for doors. an employee takes a random sample of name plates, measures the length of each name (in inches), and counts the number of letters in each name. she generates the scatterplot and trend line equation shown below. a customer would like the company to build him a name plate that is 22 inches long. what is the best estimate of the number of letters the company can have on the name plate? a. 9b. 10c. 12d. 39

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb. the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
