The average number of children from a random sample of 900 households in a city in Indiana is 1.12 children. The standard deviation from the sample was 2.4 children. a) (8 pts) Construct a 99% confidence interval for the mean number of children in all Indiana households. List the upper and lower bounds of the interval and the margin of error. Show your work. Use 2 decimal places for the upper and lower bounds. Do not round the margin of error.

In a sample of 80 households, the average number of children was 1.81 with a sample standard deviation of 1.67. Construct a confidence interval estimate at the 90% confidence level. Round your answer to four places beyond the decimal point and make sure to fully calculate the interval.

Confidence interval for the average number of children in a household based on a simple random sample was used to construct this interval. Assuming a normal approximation was used, find the 95% confidence interval for the average number of children per household.

A 90% confidence interval for the average number of children per household based on a simple random sample is found to be (0.7, 2.1). Assuming that the Normal approximation was used to construct this interval, find the 95% confidence interval for the average number of children per household. Show full mathematical statistics working out of your answer. Don't explain your working out in writing sentences.
