Question 4
You have recorded the minutes it takes for the delivery of
your pizza during the last 10 Fridays, and the times are: {39, 28,
20, 27, 36, 37, 23, 35, 43, 42}.
State first any assumptions and then calculate a 95%
confidence interval of the population mean of delivery time.

A
pizza delivery chain advertises that it will deliver your pizza 25
minutes from when the order is placed. A random sample of 13
customers recorded the time it took for their pizzas to be
delivered and found that the mean time was 27.2 minutes, with a
standard deviation of 4.3 minutes. Assume the population of
delivery times is normally distributed and test the claim that the
mean pizza delivery time is 25 minutes using a 5% level of
significance....

A local pizza place claims that they average a delivery time of
7.32 minutes. To test this claim, you order 11 pizzas over the next
month at random times on random days of the week. You calculate the
average delivery time and sample standard deviation from the 11
delivery times (minutes), and with the sample mean and sample
standard deviation of the time (minutes), you create a 95%
confidence interval of (7.648, 9.992). (delivery time is normally
distributed)

A research council wants to estimate the mean length of time (in
minutes) that the average U.S. adult spends watching television
using digital video recorders (DVR’s) each day. To determine the
estimate, the research council takes random samples of 35 U.S.
adults and obtains the following times in minutes.

A customer wants to estimate the average delivery time of a
pizza from the local pizza parlor. The customer wants to obtain a
sample mean that falls within 3.212 minutes of the true average
delivery time with 90% confidence. If the customer knows the
standard deviation of the delivery times of all pizzas is 11.959,
how many pizzas will need to be ordered?

You are the manager of a restaurant that delivers pizza to
customers. You have just changed your delivery process in an effort
to reduce the time between the order and the completion of delivery
from the current 25 minutes. From past experience, you can assume
that the population standard deviation is 6 minutes. A sample of 36
orders using the new delivery process yields a sample mean of 22.4
minutes.
