1. The table below shows the distribution of cholesterol level (in mg/dL) for 6,000 children. The class intervals include the left endpoint, but exclude the right one.

a) Plot the histogram. Mark the horizontal and vertical scales

b) Label the axes and indicate units on both. Describe the shape of the distribution.

b) Estimate the median and the third quartile. Explain

c) What is your guess for the average cholesterol level. Explain.

d) Are there more children with cholesterol level 100 or 200? Explain your answer. e) Are the children with cholesterol level between 140 and 200 mg spread fairly evenly over that range? Explain your answer.

The average cholesterol level in the general US population is 189 mg/dL. A researcher wants to see if the average cholesterol for men in the US is different from 189 mg/dL. She takes a sample of 81 American males and finds a sample mean of 194 mg/dL and a sample standard deviation of 10.4. Create a 90% confidence interval for the true average cholesterol level of the general US male population. What is the 90% confidence interval? What is the...

The CDC defines “high cholesterol” as having total cholesterol of 240 mg/dL or higher, “borderline high” as having a total cholesterol of more than 200 but less than 240, and “healthy” as having total cholesterol of 200 or less.
