A market research company wishes to know how many energy drinks adults drink each week. They want to construct a 90% confidence interval for the mean and are assuming that the population standard deviation for the number of energy drinks consumed each week is 1.3. The study found that for a sample of 1083 adults the mean number of energy drinks consumed per week is 3.5. Construct the desired confidence interval. Round your answers to one decimal place.

An important problem in industry is shipment damage. A pottery producing company ships its product by truck and determines that it cannot meet its profit expectations if, on average, the number of damaged items per truckload is greater than 11. A random sample of 15 departing truckloads is selected at the delivery point and the average number of damaged items per truckload is calculated to be 11.3 with a calculated sample of variance of 0.64. Select a 90% confidence interval for the true mean of damaged items.a) [10.68, 11.92]b) [10.64, 11.36]c) [53.67, -33.86]d) [-0.3635, 0.3635]e) [10.94, 11.66]

An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 171 lb. The new population of pilots has normally distributed weights with a mean of 136 lb and a standard deviation of 28.1 lb. a. If a pilot is randomly selected, find the probability that his weight is between 130 lb and 171 lb.
