nutrient supplementation for her class. She learned that dietary
supplements, such as a balanced multivitamin and mineral

The manager of store A is aware that waiting times are much
longer if the customer makes an order with a special request. From
past experience this occurs 20% of the time. If we monitor the next
10 customers,
(a) What is the probability that half or more of these customers
make a special request?
(b) What assumptions do you need to make to find this
probability? Out of the next 100 customers,
(c) There is a probability of 90%...

Zingo's Grocery store claims that customers spend an average of
5 minutes waiting for service at the stores deli counter. A random
sample of 45 customers was timed at the deli counter, and the
average service time was found to be 5.75 minutes. Historically the
standard deviation for waiting time is 1.75 minutes per
customer.
a. Find the 95% confidence interval for
the mean time that customers wait at the deli counter.
b. Is there sufficient evidence to...

ETHICS Suppose that, while waiting in line at the grocery store,
you overhear a stranger saying that the FDA is going to approve a
new drug tomorrow—one that will be a huge success for Alpha
Pharmaceuticals. Is it legal for you to buy stock in Alpha? Is it
ethical? What would Kant and Mill say?

The distribution of the number of people in line at a grocery
store checkout has a mean of 3 and a variance of 9. A sample of the
numbers of people in 50 grocery store checkout lines is taken.
(a) (3 points) What’s the probability that the sample mean is
less than 4.5? Round your answer to four (4) decimal places.
