n a certain country, the heights of adult males have a mean 170cm and standard deviation of 10cm, and the heights of adult females have mean 160cm and standard deviation of 8cm; for each sex the distribution of heights approximates closely to a normal probability model. On the hypothesis that height is not a factor in selecting a mate, calculate the probability that 1. a husband and wife selected at random are both taller than 164cm 2. in a randomly selected husband and wife, the wife is taller than the husband 3. the average height of a random couple is greater than 168cm

A semi-truck can transport a maximum of 14,950 pounds. Suppose that a load of cargo containing 115 boxes needs to be transported via this semi-truck. Research has shown that the weights of boxes for this type of cargo have a distribution that has a population mean weight of 125 pounds and a population standard deviation of 20 pounds. Based on this information, what is the probability that all 115 boxes can be safely loaded into the semi-truck and transported?
An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 150 lb and 201 lb. The new population of pilots has normally distributed weights with a mean of 157 Ib and a standard deviation of 34.1 Ib. a. If a pilot is randomly selected, find the probability that his weight is between 150 lb and 201 Ib. The probability is approximately (Round to four decimal places as needed.) b. If 33 different pilots are randomly selected, find the probability that their mean weight is between 150 lb and 201 Ib. The probability is approximately (Round to four decimal places as needed.)

Many consumers pay careful attention to stated nutritional contents on packaged foods when making purchases, so it is important that the information on packages be accurate. Suppose that a random sample of n = 12 frozen dinners of a certain type was selected and the calorie content of each one was determined. Below are the resulting observations, along with a boxplot and normal probability plot.
