The heights of young American women, in inches, are normally distributed with mean mu andstandard deviation o = 2.4. I select a simple random sample of four young American women andmeasure their heights. The four heights, in inches, are {63, 69, 62, 66}. Based on these data, if I wantthe margin of error for a 99% confidence interval to be ± 1 inch, I should select a random sample ofsizeO 2O 7O 16O 39

Given that Population SD = 2.4 Margin of error E = 1 Confidence level = 99%

Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is 3 inches. The heights of 6 randomly selected students are 71, 73, 69, 72, 71 and 64. x= Margin of error at 99%= confidence level = 99% confidence interval = [smaller value, larger value]=
The newest model of a car battery from a popular brand is supposed to have a lifetime of 60 months, but the lifetime varies slightly from battery to battery. It is known that the population of all lifetimes (in months) of this model of car battery is approximately normally distributed. You are a product reviewer who wants to estimate the standard deviation for this population with a random sample of 22 car batteries. Follow the steps below to construct a 99% confidence interval for the population standard deviation of all lifetimes of this model of car battery. (If necessary, consult a list of formulas.)

The Florida Department of Transportation (FDOT) would like to estimate the average speed of vehicles on 95. The mean speed , in miles per hour , of a random sample of vehicles was found to be 73 miles per hour. The standard deviation of the speeds of all vehicles on 1 - 95 is known to be 15 miles per hour . Find three different confidence intervals one with sample size 103, one with sample size 231, and one with sample size 370. Assume that the mean of each sample is 73 miles per hour . Notice how the sample size affects the margin of error and the width of the interval. Report confidence interval solutions using interval notation . Round solutions to two decimal places, if necessary .

A car manufacture produces a new car that advertises an average of 30 MPG. The distribution of MPG of cars is normally distributed. The manufacturer will test 30 cars off the assembly line to find a confidence interval of the average MPG of their new vehicle to determine if it is close to 30. The average MPG of the 30 cars is 31.2 gallons with a standard deviation of 2 gallons. Find a 95% confidence interval for the average MPG of the new vehicle. (30.45, 31.95) (30.48, 31.92) O (31.18, 31.22) O The sample size is too small to compute a confidence interval.
An agricultural researcher plants 14 plots with a new variety of corn. The average yield for these plots is X = 155 bushels per acre. Assume that the yield per acre for new variety of corn follows a normal distribution with unknown mean and a calculated sample standard deviation s = 10 bushels. A 90% confidence interval for the unknown mean is
A city planner wants to estimate the average monthly residential water usage in the city. He selected a random sample of 42 households from the city, which gave the mean water usage to be 3409.30 gallons over a one-month period. Based on earlier data, the population standard deviation of the monthly residential water usage in this city is 387.90 gallons. Make a 97% confidence interval for the average monthly residential water usage for all households in this city.
