b. Compute the standard deviation
c. Find the probability that exactly 10 murders are committed with
a firearm.
d. Find the probability that at most 11 murders are committed with
a firearm.

are committed with a firearm. Suppose 15 murders are randomly
selected. First construct a relative and cumulative frequency
distribution for the situation. Then confirm that it is both a
probability and binomial probability distribution.
a. Compute the mean.
b. Compute the standard deviation.
c. Would a sample of 15 with 6 murders committed with a
firearm be considered unusual? Justify your reasoning.
d. Find the probability that exactly 10 murders are...

According to a report,
64.764.7%
of murders are committed with a firearm.(a) If
300300
murders are randomly selected, how many would we expect to be
committed with a firearm?(b) Would it be unusual to observe
204204
murders by firearm in a random sample of
300300
murders? Why?
(a) We would expect
nothing
to be committed with a firearm.
(b) Choose the correct answer below.
A.
YesYes,
because
204204
is greater than mu plus 2 sigma .greater than μ+2σ.
B.
NoNo,...
