The NiHoMah Consulting Group sent their top executive, Yuan, to investigate the safety of a proposed water taxi from Long Beach to Catalina Island. It is known that men are heavier than women on average, so a worst case situation would be to have an all male group of passengers. If he found that, nationally, the average weight of men was 175 pounds with a standard deviation of 30 pounds, help him a. Find the probability that the weight of...

Assuming that men's weights are normally distributed with a mean of 172 lb. and a population standard deviation of 29 lb, find the probability. a.) That a randomly selected man has a weight greater than 180 lb. (4 points) b.) That 36 randomly selected men have a mean weight of less than 167 lb. (4 points)

The blood pressure for men aged 18 to 29 is modeled with a normal density curve. The distribution has a mean of ? = 120 and a standard deviation of ? = 10. The following is the random variable distribution with the normal density curve. Use this to answer the following questions. SHOW WORK! a. (2 point) If a man has a blood pressure of 105 how many standard deviations away from the mean is his blood pressure? b. (2...

1. Assume that the weights of a particular group of men follow approximately a normal distribution with a mean of 168.7 pounds and a standard deviation of 13.5 pounds. Use built-in functions of your calculator (write down what you entered in one line) or Table A.2. to answer the following questions. No credit if you use the Rule covered in Chapter 7. Show your work to receive credit. Clearly state the answer. a) What percent weigh between 160 and 190...

A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken. a.What is the distribution for the weights of one 25-pound lifting weight? What is the mean and standard deviation? b.What is the distribution for the mean weight of 100 25-pound lifting weights? c.Find the probability that the mean actual weight for the...

birth weights of full-term babies in a certain region are normally distributed with mean 7.125 pounds and standard deviation 1.290 pounds,find the probability that a randomly selected new born will weigh less than 5.5 pounds
Ski Gondola find the probability
2. A ski gondola in Vail, CO, carries skiers to the top of a mountain. It bears a plaque stating the maximum capacity is 12 people of 2004 pounds. That capacitywill be exceeded if 12 people have weights with a mean greater than 2004/12 = 167 pounds. Because men tend to weigh more than women, a “worse case” scenarioinvolves 12 passengers who are all men. Men have weights that are normally distributed with a mean of 172 pounds with a...

The weights of adult giraffes follow a normal distribution with mean 2200 pounds and standard deviation 200 pounds. What is the probability that a randomly selected adult giraffe weighs more than 2350 pounds? a) 0.227 b) 0.273 c) 0.469 d) 0.518 e) 0.773

1) The weights of newborn children in the U.S. vary according to the normal distribution with mean 7.5 pounds and standard deviation 1.25 pounds. The government classifies newborns as having low birth weight if the weight is less than 5.5 pounds. a) What is the probability that a baby chosen at random weighs less than 5.5 pounds at birth? b) Suppose we select 10 babies at random. What is the probability that their average birth weight is less than 5.5...
