46% of all violent felons in the prison system are repeat
offenders. If 45 violent felons are randomly selected, find the
probability that
a. Exactly 21 of them are repeat offenders.
b. At most 23 of them are repeat offenders.
c. At least 19 of them are repeat offenders.
d. Between 18 and 25 (including 18 and 25) of them are repeat
offenders.

Find the equation of the regression line for the given data.
Then construct a scatter plot of the data and draw the regression
line. (The pair of variables have a significant correlation.)
Then use the regression equation to predict the value of y for each
of the given x-values, if meaningful. The table below shows the
heights (in feet) and the number of stories of six notable
buildings in a city.

Given two dependent random samples with the following
results:
Population 1 45 46 27 36 38 33 15
Population 2 42 32 42 41 25 28 19
Use this data to find the 95% confidence interval for the true
difference between the population means. Let d = (Population 1
entry -- (Population 2 entry). Assume that both populations are
normally distributed.
Solution:
Step 1. Find the mean of the paired differences, d-bar . Round
your answer to one decimal place....
