Gather all the confidence intervals that the class constructed in Exercise 7.2, and make a graph plotting each interval as a vertical line. The population mean of the 98 cholesterol measurements is 279.5 mgA00 mL.
How many intervals cross a horizontal line μ = 279.5 mg/100 rnL? About how many would you expect to cross a line μ = 279.5 mg/100mL?
