EX16_XL_CH08_GRADER_CAP_HW – Customer Satisfaction 1.5
Project Description:
You have been hired to analyze the effectiveness of a local restaurant’s drive-through service. As part of your
analysis, you will evaluate customer satisfaction. You hypothesize that customer satisfaction decreases as wait
time increases. You also believe there is a correlation between the quality of the food and overall satisfaction.
You have collected a cross-section sample of 30 customers’ wait time and satisfaction level surveys based on the
range of 1 to 5, with 1 being least satisfied and 5 being most satisfied. You have also pulled a random sample of
10 surveys to evaluate wait time satisfaction.
Instructions:
For the purpose of grading the project you are required to perform the following tasks:
