A manufacturing company produces electric insulators. If the insulators break when in use, a short circuit is likely to occur. To test the strength of the insulators, destructive testing is carried out to determine how much force is required to break the insulators. Force is measured by observing how many pounds must be applied to an insulator before it breaks. The accompanying data are collected from a sample of 30 insulators.
Compute the mean, median, range, and standard deviation for the force needed to break the insulators.

insulators break when in use, a short circuit is likely to occur.
To test the strength of the insulators, destructive testing in
high-powered labs is carried out to determine how much force is
required to break the insulators. The force is measured by
observing how many pounds must be applied to the insulator before
it breaks. The force measurements, collected from a sample of 30
insulators and stored in the Force are:...

A company produces electric motors for use in home appliances.
One of the company’s managers is interested in examining the
relationship between delivery costs in a month and the number of
motors produced that month that were returned by dissatisfied
customers (Y). He has collected the data in the file.Write the
theoretical formula and calculate using excel the r-square of the
regression equation and interpret the result.

Morelli Electric Motor Corporation manufactures electric motors
for commercial use. The company produces three models, designated
as standard, deluxe, and heavy-duty. The company uses a job-order
cost-accounting system with manufacturing overhead applied on the
basis of direct-labor hours. The system has been in place with
little change for 25 years. Product costs and annual sales data are
as follows:
