Question
I’m not sure how to do number 3 can you help me be able to solve it? It’s working with confidence intervals. 
A SULIaI WUFREF Cohducted an 8-week assertiveness training workshop. Afterward the 14 clinets took the Door Manifest Assertiveness Test, which has a national mean of 24.0. Use the following data to construct a 95% confidence interval about the population mean from which your sample was drawn. Was the workshop effective? 24 25 31 25 33 29 21 22 23 32 27 29 30 27 3. Airplane manufacturers use only slow-burning materials. For the plastic in coffee pots the maximum burn rate is 4 inches per minute. An engineer randomly sampled from a case of 120 coffee pots and obtained burn rates of 1.2, 1.1, and 1.3 inches per minute. Calculate a 99.9% confidence interval and write an interpretation that tells about using these coffee pots in airplanes. . A) What is the 95% Cl of a population mean when the mean of a sample is 10, the standard deviation is 2, and the sample size is 100? a.61- 10.39 B) What is the 95% Cl of a population mean when the mean of a sample is 10, the standard deviation is 2, and the sample size is 25? 9.22-10.78 C) discuss the difference in these Cis. What is the relationship between the Cl range and sample size?
