Find the mean single charge duration time of a battery.
A team of UMD students have invented an inhalable drug that
they think will help people breathe better during hard exercise.
They test the drug on 3 volunteers (A, B, and C) by measuring
their levels of arterial oxygen before receiving the drug (their
base level) and then after 5 and 10 minutes have elapsed,
respectively. The results are listed in the table.
Oxygen level [mmHg] A B C
base level
847076
after 5 minutes
85 74 81
after 10 minutes
90 75 98
We want to see how the drug work (better or worse) when
compared to the base level. Compute the 90% two-sided
confidence intervals for the mean difference between the base
level and after 5 minutes.
