1. (15 pts) 52% of adults in the United States are women and 48% are men. The heights of the men follow an approximately normal distribution with mean 69.1 inches and standard deviation of 2.9 inches. The heights of the women are approximately normally distributed with mean 64.5 inches and a standard deviation of 2.7 inches. Suppose that we select 10 adults at random from the U.S. population.

If a simulation produced a random selection of 10 adults with

The average height as 68.186572 inches

Max height of 73.16397 inches

A) Calculate the 95% prediction interval for the average height of a random sample of 10 adults

B) Calculate 95% prediction interval for the maximum height of a random sample of 10 adults.

Solutions

Expert Solution

For the above we have to work out the confidence interval for 1) Average Height 2) Maximum height

In Europe and North America women tend to outnumber men. For example, in the United Kingdom, France, and the United States the ratio of women to men exceeds 1.05. In many Third World countries, however, especially in Asia and north Africa, the female:male ratio may be as low as 0.95 (Egypt), 0.94 (Bangladesh, China, and west Asia), 0.93 (India), or even 0.90 (Pakistan). These differences are relevant to an assessment of female inequality across the world.[1-6] Everywhere about...
