The effect of exercise on the amount of lactic acid in the blood of
sportsmen was examined in a study. Eight males were selected at random
from those attending a week-long training camp. Blood lactate levels
(micrograms/L) were measured on each volunteer before and after playing
three games of racquetball, with results as shown in the following

a) Is this paired or unpaired data?
b) Calculate the summary statistics relevant to this problem
c) Compute a 95% confidence interval for the mean change in blood lactate level.
Show all your working.
d) Based on that confidence interval, is there sufficient evidence to
conclude that the blood lactate level rises as a result of training?
e) The investigators want to estimate the mean change in blood
lactate level to an accuracy of ± 1.0 micrograms per Litre with 95%
confidence, using the same measurement process (with a known standard
deviation of 4). How many
