A manufacturing company produces electric insulators. You define the variable of interest as the strength of the insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks. The data shown below represent the amount of force required to break a sample of 30 insulators. Complete parts a through c below. 9 10 7 7 15 19 22 24 15 35 15 30 25 22 30 31 28 29 39 62 10 6 42 40 15 22 23 24 25 25 Construct a 99% confidence interval for the population mean force.

A manufacturing company produces electric
insulators. You define the variable of interest as the strength of
the insulators. If the insulators break when in use, a short
circuit is likely. To test the strength of the insulators, you
carry out destructive testing to determine how much force is
required to break the insulators. You measure force by observing
how many pounds are applied to the insulator before it breaks. You
collect the force data for 30 insulators selected for the...

A manufacturing company produces electrical insulators. If the
insulators break while 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 the number of pounds of
force applied to the insulator before it breaks. Data are available
in the worksheet labeled “Problem 1”

Otacnu Manufacturing Inc. builds 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 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:...

(i) Define in words the strength of an electric field at a given
point in space.
(ii) An electron experiences an acceleration of magnitude 2.0 ×
1013 ms−2 in the positive x-direction, due to
a uniform electric field. Calculate the magnitude and direction of
the electric field.

The tensile strength of a fiber used in manufacturing cloth is
of interest to the purchaser. Previous experience indicates that
the standard deviation of tensile strength is 2 psi. A random
sample of eight fiber specimens is selected, and the average
tensile strength is found to be 127 psi. USING MINITAB
(please show all work)
(a) Test the hypothesis that the mean tensile strength equals
125 psi versus the alternative that the mean exceeds 125 psi. Use a
