8.2.5 An article in Obesity Research [“Impaired Pressure
Natriuresis in Obese Youths” (2003, Vol. 11, pp. 745–751)]
described a study in which all meals were provided for 14 lean
boys for three days followed by one stress test (with a video-game
task). The average systolic blood pressure (SBP) during the
test was 118.3 mm HG with a standard deviation of 9.9 mm
HG. Construct a 99% one-sided upper confidence interval for
mean SBP.

Exercise [“Maximal Leg-Strength Training Improves Cycling
Economy in Previously Untrained Men” (2005, Vol. 37, pp.
131–136)] studied cycling performance before and after 8 weeks
of leg-strength training. Seven previously untrained males performed leg-strength training 3 days per week for 8 weeks (with
four sets of five replications at 85% of one repetition maximum).
Peak power during incremental cycling increased to a mean of
315 watts with a standard deviation of 16 watts. Construct a 95%
