(a)
The following data shows the number of hours that 8 hospital
patients slept following the administration of a certain
anesthetic.
8, 5, 12, 10, 11, 4, 6, 10,
Find a 95% confidence interval for the average hours slept
following the administration of the anesthetic for the sampled
population.

The following data is the survival time of a set of patients
who had Glioblastoma (it is the time from detection until death):
{5.28, 6.36, 9.72, 0.25, 5.52, 0.24, 76.8, 15.12, 11.52, 21.84,
2.76, 5.4, 15, 4.8, 1.08}.
Determine a 90% confidence interval for the median of the data
and a 90% confidence interval for the mean of the data.

The PulseRates data set has pulse, height and weight for 90
patients who had an echocardiogram test in one of the clinic in
Ottawa in the month of September. (a)[2] Fit a L-S regression line
using height to predict the pulse rate (pulse rate is called the
response variable). What is the equation of the L-S regression
line? . Does it make sense to use this line? Why? (Check the
correlation coefficient)

Chapter 8. A sample of
36 patients in a doctor's office showed that they had to wait an
average of 45 minutes with a standard deviation of 12 minutes
before they could see the doctor.
Please provide a 95%
confidence interval estimate for the average waiting time of all
the patients who visit this doctor, and interpret your results
(write a sentence explaining the results).
