A drapery store manager was interested in determining whether a new employee can install vertical blinds faster than an employee who has been with the company for two years. The manager takes independent sample of 10 vertical blind on installations of each of the two employees and computes the following information. Test whether the new employee installs vertical blinds faster, on the average, than the veteran employee, at the level of significance 0.05.
| New Employee | Veteran Employee | |
| Sample Size | 10 | 10 |
| Sample Mean | 22.2 min | 24.8 min |
| Sample Standard Deviation | 0.90 min | 0.75 min |
Let
m1 = true average time takes a new employee to install vertical blinds
and
m2 = true average time takes a veteran employee to install vertical blinds

Please and Thanks.
Domino’s Pizza was interested in determining whether a new
employee could learn how to make a pizza using a computer-based
training method (CD-ROM). The CD-ROM application addresses the
proper procedure for “massaging” a dough ball and stretching it to
fit a 12-inch pizza pan. Domino’s quality standards emphasize the
roundness of the pizza, an even border, and uniform thickness of
the dough. Traditionally, on-the-job training is used to teach new
employees how to stretch pizza dough to...

The manager at the Lawrence National Bank is interested in
determining whether there is a difference in the mean time that
customers spend completing their transactions depending on which of
four tellers the use. To conduct the test, the manager has selected
simple random samples of 15 customers for each of the tellers and
has timed them (in seconds) from the moment they start their
transaction to the time the transaction is completed and they leave
the teller station. The...

a. The marketing manager for an automobile manufacturer is
interested in determining the proportion of new compact-car owners
who would have purchased a passenger-side inflatable air bag if it
had been available for an additional cost of $300. The manager
believes from previous information that the proportion is 0.30.
Suppose that a survey of 200 new compact-car owners is selected and
79 indicate that they would have purchased the inflatable air bags.

The manager of a
coffee shop called Perks is interested in determining if a new
ordering system that a competitor's store, Cool Beans, has been
using might make service time quicker on average at his store.
Minor differences in mean service time are to be expected, but a
decrease of more than 30 seconds using the new system would be
practically significant to the manager of Perks and allow him to
conclude the new technology would be useful for his...
