A new operator was recently assigned to a crew of workers who perform a certain job. From the records of the number of units of work completed by each worker each day last month, a sample of size five was randomly selected for each of the two experienced workers and the new worker. At the α = .05 level of significance, does the evidence provide sufficient reason to reject the claim that there is no difference in the amount of work done by the three workers?
| Workers | |||
| New | A | B | |
| Units of work (replicates) | 8 | 12 | 10 |
| 10 | 12 | 9 | |
| 9 | 12 | 10 | |
| 9 | 11 | 11 | |

decimal places.)
(ii) Find the p-value. (Give your answer bounds
exactly.)

4. You manage a crew of 160 workers who could be assigned to
make either of two products. Product A requires two workers per
unit of output. Product B requires four workers per unit of output.
a) Write an equation to express the combinations of products A and
B that could be produced using exactly 160 workers. b) Measuring
the quantity of product A on the horizontal axis and the quantity
of product B on the vertical axis, use vertical...

To compare two programs for training industrial workers to
perform a skilled job, 12 workers are included in an experiment. Of
these, 5 workers are selected at random and trained by method 1;
the remaining are trained by method 2. After completion of
training, all the workers are subjected to a time-and-motion test
that records the speed of performance of a skilled job. The
following data are obtained.
Method 1 - 15 20 11 23 16
Method 2 - 23...

In a small job shop department there
are four jobs to be assigned to three workers. The table below
indicates the weekly costs incurred by assigning each worker to
each job. The objective is to find the optimal assignment that will
minimize the total cost.

Gloria and Lakeisha are co-workers who are assigned to work on a
project together. Lakeisha is very organized and wants them to do
really well on this project. To help them get started, Lakeisha
took some initiative and prepared a list of to-do items along with
due dates. She even color-coded the list to indicate which partner
will do each item and sends an email to Gloria with the to-do list.
Lakeisha wants her partner to know that she’s serious...

The time T (in minutes) required to perform a certain job is
uniformly distributed over the interval [15; 60], which means that
T is equally likely to take on any value in [15; 60] while it is
impossible to take on any value outside that interval. 1 MATH 32
Worksheet 05: Chapter 5 Fall 2018 (a) Write down the probability
mass function of T. (b) Find the probability that the job requires
more than 30 minutes. (c) Given that the...

The time it takes a randomly selected job applicant to perform a
certain task has a distribution that can be approximated by a
normal distribution with a mean of 120 seconds and a standard
deviation of 20 seconds. The fastest 10% are to be given
advanced training. What task time qualifies individuals for such
training? (Remember the fastest times takes the least amount of
time.) Use Excel to find your answer .Round your answer to the
nearest second.

Scenario
#1
You are assigned to
care for a patient who was recently admitted to your unit with
pneumonia and is ordered antibiotics. The physician starts with a
cephalosporin (ceftriaxone) to attack the bacteria.
When completing your initial assessment and patient history what
would be concerning to you as the RN?
What side effects and adverse reactions will you be monitoring
for while the patient is taking a cephalosporin?
What are the contraindications and interactions of
cephalosporins?
What are the...

Technology has led to the rise of extreme workers who are on the
job 60 hours a week or more. One of the reasons cited by employees
about why they work long hours was that they loved their job
because it was stimulating. Suppose that the survey of 1564
workaholics included 786 men and 778 women, and 707 men and 638
women loved their job because it is stimulating. At the 0.05 level
of significance, you would like to determine...
