As part of a research program for a new cholesterol drug, a pharmaceutical company would like to investigate the relationship between the ages and LDL (low-density lipoprotein) cholesterol of men. The following data set shows the ages and LDL cholesterol levels of seven randomly selected men. Construct a 95% confidence interval to estimate the average LDL cholesterol level of a 31-year-old man. Click the icon to view the data table. Determine the upper and lower limits of the confidence interval. UCL LCL = (Round to one decimal place as needed.).
