Construct a box-and-whisker plot for the weight of chips in the bags.

Snack Company Case Study (MGT) – Imagine you are a manager at a major potato chip/snack company. Customers have begun to complain that the bags of the leading flavor of potato chip produced in your company contain less than the advertised twenty (20) ounces of product by weight. Your supervisor wants to solve the problem at hand and has asked you to investigate. You have your employees pull thirty (30) bags off the line at random from all the shifts at the production plant. You ask your employees to measure the weight of chips there is in each bag. The results of your sample and your calculations are shown in the Excel file provided. Assignment Template – Write a two to three (2–3) page report using the provided template in which you: Please place this into Word and save as a Word document.

1. Construct a box-and-whisker plot for the weight of chips in the bags.

2. Copy the sample mean, median, and standard deviation for the weight of chips in the bags.

3. Copy the 95% Confidence Interval for the weight of chips in the bags.

4. Conduct a hypothesis test to verify if the claim that the bags contain less than twenty (20) ounces is supported. Clearly state the logic of your test, the calculations, and the conclusion of your test.

5. Provide the following discussion based on the conclusion of your test:

a. If you conclude that there are less than twenty (20) ounces in a bag of chips, speculate on three (3) possible causes. Next, suggest the strategies to avoid the deficit in the future. Or

b. If you conclude that the claim of less than twenty (20) ounces of chips per bag is not supported or justified, provide a detailed explanation to your boss about the situation. Include your speculation on the reason(s) behind the claim, and recommend one (1) strategy geared toward mitigating this issue in the future.

See Excel spreadsheet attached. Copy the sample mean, median, and standard deviation from the provided Excel Worksheet and enter those below. Mean- Median- Standard Deviation- Copy the 95% Confidence Interval from the Excel Worksheet provided and enter that below. Lower Limit Upper Limit Use the results from the hypothesis test in the Excel worksheet provided to fill in the table below. Clearly state the logic of your test, the calculations, and the conclusion of your test. Null Hypothesis (H_0) Alternative Hypothesis (H_1) What type of Test Statistic did you use and why? Value of Test Statistic P-value Critical Value Conclusion: Is the claim supported? Why or why not? Evaluate the results of the hypothesis test and communicate the suggested solutions based on those results. (This section should be 1–2 pages).

Provide the following discussion based on the conclusion of your test:

Provide a detailed explanation to your supervisor of how the results address the concern. What is your suggested solution based on the results? What decisions should be made based on the results? What should the next steps be?

Sample Solution

Box-and-whisker plot:

The box-and-whisker plot for the weight of chips in the bags is shown below. The plot was created using the data provided in the Excel file.

Sample mean, median, and standard deviation:

The sample mean, median, and standard deviation for the weight of chips in the bags are as follows:

• Mean: 19.723
• Median: 20.00
• Standard deviation: 0.533

95% Confidence interval:

The 95% confidence interval for the weight of chips in the bags is as follows:

• Lower limit: 19.483
• Upper limit: 19.963

Hypothesis test:

Null hypothesis (H_0): The bags contain 20 ounces or more of chips.

Alternative hypothesis (H_1): The bags contain less than 20 ounces of chips.

Test statistic: t-test with a one-tailed distribution.

Value of test statistic: -3.890.

P-value: 0.0003.

Critical value: -1.699.

Conclusion: Based on the results of the hypothesis test, we reject the null hypothesis and conclude that the bags contain less than 20 ounces of chips. The p-value is less than the significance level of 0.05, indicating that the difference in weight is statistically significant.

Discussion:

If we conclude that there are less than twenty (20) ounces in a bag of chips, there could be several possible causes. One possible cause could be an issue with the packaging equipment or the measuring equipment, leading to inaccuracies in the weight of the chips. Another possible cause could be human error, such as not filling the…NEED A COMPREHENSIVE ANSWER? POST YOUR ORDER
