Question 1: The director of a green energy
company is interested in comparing two different methods of
installing solar light panels. An experiment is conducted with 31
technicians using the old method and the other 46 technicians using
the new method. For the 31 technicians using the old method, the
average time was 525 minutes with 47.7 standard deviation. For the
46 technicians using the new method, the average time was 520
minutes with 48.2 standard deviation. Conduct an analysis to
determine whether there is a difference in the average time to
complete the installation of the solar panels. Provide the test
statistic value.
Question 2:
The director of a green energy company is interested in
comparing two different methods of installing solar light panels.
An experiment is conducted with 39 technicians using the old method
and the other 55 technicians using the new method.
For the 39 technicians using the old method, the average time was
582 minutes with 63.8 standard deviation.
For the 55 technicians using the new method, the average time was
542 minutes with 97.8 standard deviation.
Conduct an analysis to determine whether there is a difference in
the average time to complete the installation of the solar panels.
Provide the degrees of freedom.

A manufacturing company is comparing the time needed to build a
product using two different assembly methods, A and B. Sample data
compiled from each method appears below. Using the 5% significance
level, test the claim that the mean time needed for Method A is
less than that of Method B (claim: μA <
μB) by choosing the correct answer below.
Test statistic: ‒2.64, Critical value(s): ‒1.645, Conclusion:
The data support the claim that the mean time for Method A...

Suppose an investigator is interested in comparing the weight
(ounces) of components produced by two different machines. They are
interested in being able to detect a difference of 0.25 ounces
between average weights of the components produced by the two
different machines, and they believe the variance of the weights
will be equal for the two machines being studied. They are
conducting a two-sided test with a significance level of a = 0.05.
Using preliminary data they have estimated the...

A researcher was interested in comparing the response times of
two different cab companies. Companies A and B were each called at
50 randomly selected times. The calls to company A were made
independently of the calls to company B. The response times for
each call were recorded. The summary statistics were as
follows:
Company A
Company B
Mean response time
7.6 mins
6.9 mins
Standard deviation

A consumer group was interested in comparing the operating time
of cordless toothbrushes manufactured by two different companies.
Group members took a random sample of 18 toothbrushes from Company
A and 15 from Company B. Each was charged overnight and the number
of hours of use before needing to be recharged was recorded.
Company A toothbrushes operated for an average of 117.7 hours with
a standard deviation of 1.74 hours; Company B toothbrushes operated
for an average of 120.6 hours...

A video game company is interested in knowing the population
mean number of hours spent playing a new game from start to finish.
If the game takes longer than 50 hours to play, on average, then it
will need to be re-worked. The company collects a sample of 49
video game players with various levels of expertise, and finds that
it takes them 48 hours, on average, to complete the game, with a
standard deviation of 1.5 hours.
