Data on the numbers of hospital admissions resulting from motor
vehicle crashes are given below for Fridays on the 6th of a month
and Fridays on the following 13th of the same month. Assume that
the paired sample data is a simple random
sample and that the differences have a distribution that is
approximately normal. Construct a 95% confidence interval estimate
of the mean of the population of differences between hospital
admissions. Use the confidence interval to test the
claim...

Data from the Motor Vehicle Department indicate that 80%
of all licensed drivers are older than age 25.
a. In a sample of n=50 people who recently received
speeding tickets, 33 were older than 25 years and the other 17 were
age 25 or younger. Is the age distribution for this sample
significantly different from the distribution for the population of
licensed drivers? Use α= 0.05.
