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 accompanying data set shows the ages and LDL cholesterol levels of seven randomly selected men. Construct a 95% prediction interval to estimate the LDL cholesterol level of a 40-year-old man.
Age Cholesterol
22 141
37 177
25 160
33 196
41 157
31 140
42 209
Determine the upper and lower limits of the prediction interval. (round to 1 decimal)
The statistical software output for this problem is :
The upper and lower limits of the prediction interval are :
Upper limit = 250.9
Lower limit = 115.6
