Essay
1. Use the background information below to create the essay.
Case Study
Scenario
Land and Agua Insurance Company has a call center in Tempe, Arizona. The business
was originally established in Phoenix, Arizona in 1972 as a small business, and it has
grown with the population of the area. The insurance company specializes in bundling
insurance for cars, off-road vehicles, and watercraft (e.g., jet skis and boats). The
company has 150,000 clients in Arizona.
Marjorie Jones, Vice President of Operations, is concerned about customer complaints
and the amount of time representatives are taking to resolve the calls. You are part of
the team investigating the data to determine the probabilities of errors and call times.
Ms. Jones also wants to understand the approximate range around the average for call
times.
2. Answer the questions below in essay format. Your essay must include an introduction,
a body, and a conclusion. It must address all relevant parts of each question. Your
response should be a minimum of 500 words in length, and it should include your
analysis of the probability calculations. Make sure to cite any source you use. Proper
citation format for a source includes the name of the author(s), the title of the work,
the date of the publication, and the page number if you directly quote the source.
Essay: Probability
Using the Quality Summary and Call Center Data, provide a summary report for the vice
president including the following information in an essay with a minimum of 500 words:
1. Based on the probability of an error provided in the quality summary under call quality
using a sample size of 15, predict the probability of both < 2 errors or errors using the
correct discrete probability distribution. Assume calls are either correct or incorrect.
2. Using the call time mean and standard deviation from the quality sample, find the
probability of a call time < 7min, between 7 and 9 min, and > 9 min.
3. Calculate and evaluate the 95% confidence interval for the mean from the call time
data.
Answer:
1. P(x<2)=0.3186
2. P(x<7)=0.131; P(79)=0.752.
3. 11.07 +/- (1.98)(3.38/sqrt(150)= 10.52, 11.61

company has 150,000 clients in Arizona.
Marjorie Jones, Vice President of Operations, is concerned about customer complaints
and the amount of time representatives are taking to resolve the calls. The team must
focus on two areas from the preliminary data collection including call time and error
type by shift.
2. Answer the questions below in essay format. Your essay must include an introduction,
a body, and a conclusion. It must address all relevant parts of each question. Your
response should be a minimum of 500 words in length, and it should include both the
appropriate statistics and support for the analysis and interpretation. Make sure to cite
any source you use. Proper citation format for a source includes the name of the
author(s), the title of the work, the date of the publication, and the page number if you
directly quote the source.
Essay Questions: Hypothesis Tests
Using the Sample Hypothesis Test Data and Chi-Square Data, provide a summary report for
the vice president including the following information in an essay with a minimum of 500
words (the level of significance is .05):
•
Two-sample hypothesis test ‒ Discuss the hypothesis test assumptions and test you
used. Provide the test statistic and critical-value in your response. Evaluate the results
•
of the hypothesis test with the scenario. Provide recommendations for the vice
president.
Chi-square hypothesis test ‒ Discuss the hypothesis test assumptions and test you
used. Provide the test statistic and critical value in your response. Evaluate the results
of the hypothesis test with the scenario. Provide recommendations for the vi ce
president.
Answer:
1. T test = -12.25; p value = 0.0; since p is less than alpha, we reject the null hypothesis.
2. Chi square test = 2.6368; p value = 0.4511; since p is less than alpha, we reject the null
hypothesis.

company has 150,000 clients in Arizona.
Marjorie Jones, Vice President of Operations, is concerned about customer complaints
and amount of time representatives are taking to resolve the calls. After studying the
issue, the company implemented improvements to operations, and a new data sample
was collected after three months. You are responsible for analyzing the results to
determine whether the improvements made a difference, and determining if the new
processes are meeting customer specifications. Additionally, you must review the data
and predict the customer call time if a defect occurs.

Essay Questions: New Call Time
Using the New Call Center Data, provide a summary report for the vice president including
the following information in an essay with a minimum of 500 words:
•
Using the two-sample hypothesis test comparing old call time to new call time at a .05
level of significance, discuss the hypothesis test assumptions and tests used. Provide
the test statistic and p -value in your response. Evaluate the results of the hypothesis
test with the scenario. Provide recommendations for the vice president.
•
Using new call time and coded quality, develop a prediction equation for new call
time. Evaluate the model and discuss the coefficient of determination, signi ficance,
and use the prediction equation to predict a call time if there is a defect.
•
Evaluate whether the new call time meets customer specification. As stated in a
previous lesson, customers indicated they did not want a call time longer than 7.5
minutes. Assume a standard deviation of 2 min is acceptable. Is the call center now
meeting the customer specifications? If not where is the specification not being met?
Explain your answers.
Answer:
1. Two sample t test, t=9.952, p value=1.976, since p value is greater than alpha, we fail to
reject the null hypothesis.
2. the coefficient of determination is8.43E-05, p value = 0.9112, Y=8.8448+0.0802x.
3. you could pass this question.
