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.

Write My Essay For Me1. 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.
Write a two to three (2–3) page report in which you: Construct a box-and-whisker plot for the provided data set. Copy each of the values needed to construct a box-and-whisker plot from the Excel worksheet provided and enter those numbers below. Minimum – Maximum – Quartile 1 – (Median of first half of the data set) Quartile 2 – (Median of data set) Quartile 3 – (Median of second half of the data set) Create the box-and-whisker plot in Excel and include a screenshot of the box-and-whisker plot below. 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:
Minimum: 17.3 ounces Maximum: 19.8 ounces Quartile 1: 18.05 ounces Median: 18.6 ounces Quartile 3: 19.15 ounces
Box-and-Whisker Plot:
Sample Mean: 18.6233 ounces Median: 18.6 ounces Standard Deviation: 0.6511 ounces
95% Confidence Interval: Lower Limit: 18.2493 ounces Upper Limit: 19.9973 ounces
Hypothesis Test:
Null Hypothesis (H_0): The average weight of chips per bag is equal to 20 ounces. Alternative Hypothesis (H_1): The average weight of chips per bag is less than 20 ounces.
Type of Test Statistic Used: t-test, since the sample size is less than 30 and the population standard deviation is unknown.
Value of Test Statistic: -4.197 P-value: 0.0001614 Critical Value: -1.6991
Conclusion: Since the calculated t-value (-4.197) is less than the critical value (-1.6991), we reject the null hypothesis. Furthermore, since the p-value (0.0001614) is less than the significance level (0.05), we have sufficient evidence to support the alternative hypothesis, which means that the bags contain less than 20 ounces of chips on average.
Discussion:
Based on the conclusion of the hypothesis test, it can be inferred that the company’s customers have a legitimate complaint that the bags of potato chips contain less than the advertised 20 ounces. Three possible causes of this deficit could be errors in the production process, inaccurate weighing machines, or quality control issues. To avoid this deficit in the future, the company can implement several strategies, such as improving production methods, calibrating weighing machines regularly, or conducting random quality control checks on bags to ensure that they meet the advertised weight.
Furthermore, the company should consider labeling their bags accurately and addressing any legal implications that may arise due to false advertising. The company should also…NEED A COMPREHENSIVE ANSWER? POST YOUR ORDER
