15.15. A product is shipped in lots of size N = 2,000. Find a Dodge-Romig single-sampling plan for which the LTPD = 1%, assuming that the process average is 0.25% defective. Draw the OC curve and the ATI curve for this plan. What is the AOQL for this sampling plan?
The sampling plan that should be used is n = 490 and c = 4. If rejected lots are screened 100% and defective items replaced with good ones, the AOQL (from Table 15.9) is approximately X.XX%.
n: from Table 15.9

You assume that you can fit a linear regression model using OLS as follows: y=a+ẞX + ε You want to obtain estimates for a and B. a) Suppose every civil engineering firm in the sample has the same amount of profits. What, if any, problem would this create? Explain and justify your answer. b) If the distribution of the profits were not normal, can you use linear regression? Explain and justify your answer. c) If profits were presented in categories, would estimating a linear regression model be appropriate?

Regression Problem Sarah Anderson, the business analyst at TV Revolution, is conducting research on the dealership’s various television brands. She has collected data over the past year (2022) on the manufacturer, screen size, and price of various television brands. The data is given in the file below. You have been hired as an intern to run analyses on the data and report the results back to Sarah; the five questions that Sarah needs you to address are given below. Does there appear to be a positive or negative relationship between price and screen size? Use a scatter plot to examine the relationship. Determine and interpret the correlation coefficient between the two variables. In your interpretation, discuss the direction of the relationship (positive,…arrow_forward
- Question number 6 (4 points) Sampling assignment: A list of the top 100 universities in the world is provided in the attached file. Draw a sample of 40 universities using random sampling and include a snapshot of your results from Excel in this Microsoft Word file (2 points: 1 for generating random numbers and the other for the sample drawn from the dataset.) Draw a sample of 20 universities using systematic sampling. Make sure to randomize the data before systematic sampling; and include a snapshot from Microsoft Excel in this Microsoft Word file (2 points). You can use the following template for systematic sampling.arrow_forwardThe data provided in the following table pertains to three separate questions: One sample T-test, Two Sample T-Test, and ANOVA. The same data is also provided in Microsoft Excel file. Answer the questions provided in the table. Report your results by comparing the significance level to 5%. Additionally, state your conclusion clearly in terms of whether the null hypothesis is rejected or not rejected. Avoid using terms like "accepted" or "not accepted" in your conclusion. Question 1: A retail store manager claims that the average daily sales of the store are $1,500. You aim to test whether the actual average daily sales differ significantly from this claimed value.
