- Based on data from the National Health Board, weights of men are normally distributed with a mean of 178 lbs, and a standard deviation of 29 lbs. Find the probability that 20 randomly selected men will have a mean weight between 170 and 190.arrow_forwardThe mean weight of 18-year-old females is 126 pounds, and the standard deviation is 15.7. If a sample of 25 females is selected, find the probability that the mean of the sample will be greater than 128.3 pounds. Assume the variable is normally distributed.arrow_forwardThe average number of pounds of red meat a person consumes each year is 196 with a standard deviation of 22 pounds (Source: American Dietetic Association).

- Compute the standard deviation of the sampled proportions if p=.8 and n=50. Round to three places.arrow_forwardThe average speed on a highway is 68 mph with a standard deviation of 4 mph. A vehicle is selected at random. We need to find the probability that it violates the 70 mph speed limit. Find the area to the right of the z-score (speeding).arrow_forwardThe weights of college football players are normally distributed with a mean of 191 pounds and a standard deviation of 49 pounds.

- An airliner carries 300 passengers and has doors with a height of 78 in. Heights of men are normally distributed with a mean of 69.0 in and a standard deviation of 2.8 in. Complete parts (a) through (d). a. If a male passenger is randomly selected, find the probability that he can fit through the doorway without bending. The probability is 0.9993. (Round to four decimal places as needed.) b. If half of the 300 passengers are men, find the probability that the mean height of the 150 men is less than 78 in. The probability is (Round to four decimal places as needed.)arrow_forwardAssume that adults have IQ scores that are normally distributed with a mean of 100.6 and a standard deviation of 15. Find the probability that a randomly selected adult has an IQ greater than 121.0. The probability that a randomly selected adult from this group has an IQ greater than 121.0 is nothing.arrow_forwardthe length of animals of a species is normal with population standard deviation 9.7 inches. the probability is 0.14 that the animal is hsorter than 27 inches. find the population meanarrow_forward
