![c) Solve Part c) independently. Pfizer has just developed a medicine for COVID to alleviate the
symptoms of COVID. Still, they are concerned about the variability in the amount of time until the
medicine becomes effective. In a random sample of 8 individuals who suffer from COVID, the amount of
time (in hours) for the medicine to take effect was recorded. "?" represents missing data and some
relevant statistics are given below. Estimate with 90% confidence the variability in the amount of time for
the medicine to become effective.
Amount of time (x): 12, 16, 9, ?, 8, 4, ?, 4
