The cholesterol content of large chicken eggs is normally distributed with a mean of 200 mg and standard deviation 36 mg. Suppose it is reasonable to consider a carton of 12 large eggs as a simple random sample from all large chicken eggs. What is the probability that the cholesterol content in a randomly selected large egg is between 190 and 220 mg?

In its fuel economy economy guide, the EPA gives a variety of data on 2016 model year vehicles. If outliers are ignored, the combined city and highway gas mileage is approximately normally distributed with mean 23.0 mpg and standard deviation of 4.9 mpg. Find the probability that the mean gas mileage of a smaple of twenty 2016 model year vehicles is less than 24 mpg.
An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 191 lb. The new population of pilots has normally distributed weights with a mean of 136 lb and a standard deviation of 34.9 lb a. If a pilot is randomly selected find the probability that his weight is between 130 lb and 191 lb.

One year, the distribution of salaries for professional sports players had a mean of $1.6 million and a standard deviation of $0.7 million. Suppose a sample of 100 major league players was taken. Find the approximate probability that the average salary of the 100 players that year exceeds $1.1 million.
A research team is working on a project to study the time (in seconds) for high school male runners to finish a 400-meter race. Jimmy, a junior researcher in the team, has randomly selected a sample of 25 male runners from a high school and the time (in seconds) for each of them to complete a 400-meter race was recorded. The sample mean running time was 53 seconds. It is assumed that the running time in a 400-meter race follows a normal distribution with a population standard deviation of 5.5 seconds.(a) Give a point estimate of the population mean running time for a 400-meter race.(b) Calculate the sampling error at 95% confidence level.(c) Construct a 95% confidence interval estimate of the population mean running time for a 400-meter race.
