1. A certain town has 9,000 families.Population average mileage driven per family is 15,000 miles per year and the population SD is 2,000 miles per year. Fifteen percent of these families have no cars at all. As part of an opinion survey, a simple random sample of 900 families (from this town) is chosen. What is the chance that sample average mileage driven per family is between 14,950 and 15,100 miles per year? Use the normal approximation method with continuity...

Estimate, by simulation, the average number of children there would be in a family if all people had children until they had a girl.

in R. Estimate, by simulation, the average number of children there would be in a family if all people had children until they had a girl. Do the same if all people had children until they had at least one boy and at least one girl. How many more children would you expect to find under the second scheme than under the first in 100,000 families? (Assume that girls and boys are equally likely.)

5 In a certain northern Wisconsin town (cough...cough...Oliver), there are 100 families. 30 families have 1 child, 50 families have 2 children, and 20 families have 3 children. The children are then ranked according to age: the oldest has rank 1, second oldest rank 2, third oldest rank 3. Suppose you select a random child from the town. Find the probability mass function, expected value, and variance of the childs rank.

In a particular town 10% of the families have no children, 20% have one child, 40% have two children, 20% have three children, and 10% have four. Let T represent the total number of children, and G the number of girls, in a family chosen at random from this town. Assuming that children are equally likely to be boys or girls, find the distribution of G. Display your answer in a table and sketch the histogram.
