A new process will be testing for electroplating nickel. The current process is tested on thirty slugs, and the mean thickness of the nickel is 0.0020 m with a sample standard deviation of 0.0005 m. The new process is also tested on thirty slugs remaining a sample mean of 0.0022 m and a sample standard deviation of 0.0003 m. Assume equal variances.
(a) Does the new process result in a greater thickness of nickel? Use α = 0.05. (b) Determine the 99% confidence interval for the difference in the means.

13.0 (20 pts) An electroplating process will be used to coat the
exterior surface of a 160 mm diameter x 1.5 meter long cylinder
with silver. Determine the time in minutes to electroplate silver
to a thickness of 0.06 mm if the plating current is 15 amps.

The FDA is testing a new non-addictive painkiller. Painkillers
are tested using a pain response measuring system (higher
score = more pain felt). Painkillers on the market now
have an average rating of 62.24 on the pain response measuring
system. This new pain killer is said to be more effective. It was
tested on 34 patients and it was found that the study yielded an
average rating of 55.34 with a standard deviation of 6.85.

A programming team is in the process of testing a new software
module. As part of the effort, they need to estimate the success
rate of the module when used with a particular operating system. To
do this, they plan to run the module on a randomly selected set of
computers, record how many individual runs execute properly, and
use that result to calculate the sample success rate (p-hat, the
number of successes divided by the total number of tests)....

Hypothesis testing is used in business to test assumptions and
theories. These assumptions are tested against evidence provided by
actual, observed data. A statistical hypothesis is a statement
about the value of a population parameter that we are interested
in. Hypothesis testing is a process followed to arrive at a
decision between 2 competing, mutually exclusive, collective
exhaustive statements about the parameter’s value.
Consider the following scenario: An industrial seller of grass
seeds packages its product in 50-pound bags. A...

A consumer testing agency tested 130 makes and models of cars.
In the model below, price (in 1000s) was the dependent variable,
and the independent variables included miles per gallon (MPG),
Handling score (on a scale from 0 to 5) and Reliability score (on a
scale from 0 to 20), as well as a dummy, d_Leather, indicating that
the car has a leather interior. The residual plot for MPG is also
included.

Your supervisor said, “Integration testing is a waste of time.
If each program is tested adequately, integration testing isn’t
needed. Instead, we should move on to system testing as soon as
possible. If modules don’t interact properly, we’ll handle it
then.” Do you agree with this comment? Why or Why Not?
Write easy to understanding answer. Please Thank you
