A researcher selects a sample of n=25 individuals from a
population with a mean of μ=60 and standard deviation of σ=10 and
administers a treatment. The researcher predicts that the treatment
will increase scores. Following the treatment, the average scores
for this sample is M=65.
1. Using symbols, state the hypothesis for a one-tailed
test.
2. Calculate the z-score and place this on a standardized normal
distribution.
3. With a one-tail α=0.05, state the conclusion of these
findings.
4. Calculate...

2. We are interested in analyzing data related to the Olympics
from one decade. We are looking at individuals and if they
participated in the summer or winter Olympics and whether or not
they won a medal. Use S to denote summer and M to denote if a medal
was won. The probability that someone participated in the summer
Olympics is 72%. The probability that they won a medal is 13%. The
probability that they won a medal and it...

“A sample of 60 individuals in the Midwest showed the sample
average per person annual expenditure for prescription drugs of
$745. Suppose the population standard deviation expenditure for
prescription drugs is $300.”
a. Construct a 95% confidence interval estimate for the
population mean annual expenditure for prescription drugs in the
Midwest.
b. Is $838 in the interval from part a? What would this imply
about the population mean being $838?
c. what would happen to the width of the confidence...

Abortion is one of the most difficult and controversial moral
issues we will consider. Listen to both sides, even if it is
difficult to do. Both sides have important moral insights, even if
ultimately these insights are outweighed by the insights of the
other side. The goal of this discussion is not to convince you to
accept one position over the other, but to help you to understand
both sides. As you consider this difficult issue, it is important
to...

Suppose we are interested in bidding on a piece of land and we
know one other bidder is interested. The seller announced that the
highest bid in excess of $9,500 will be accepted. Assume that the
competitor's bid x is a random variable that is uniformly
distributed between $9,500 and $15,500.a. Suppose you bid $12,000. What is the probability that your bid
will be accepted (to 2 decimals)?b. Suppose you bid $14,000. What is the probability that your bid
will...
