Please scroll down to see the entire question. The quality control manager of an automobile parts factory would like to know whether there is a difference between the proportion of defective parts produced on different days of the work week. Random samples of 100 parts produced on each day of the week were​ selected, with the following results:                       Result: Mon Tues Wed  Thurs Fri # of defective parts: 12 7 7 10 14 # of non-defective parts: 88 93 93 90 86 At​ 5% level of significance​, is there evidence of a significant difference in the proportion of defective parts produced on the various days of the week     ​(A )​ Step-1: State the hypotheses​ ( H0 and H1​ ), and identify the claim   A. H0: Proportion of defective parts is not the same for the days of the week. ​ H1: Proportion of defective parts is the same for all days of the week   B. ​H0: Proportion of defective parts is dependent on the days of the week ​ H1: Proportionof defective parts is…

You will be applying what you have learned in this course by gathering data and running a statistical analysis.    1) To study about the relationship between height and the weight, you need to collect a sample of nine (9) people using a systematic sampling method. a. What is the population of people? b.Where and how are you going to collect your sample? c. Does your sample accurately represent your population? Why or why not? d. Collect the sample and record the data. 2) (CLO 1) Construct a confidence interval to estimate the mean height and the mean weight by completing the following: a. Find the sample mean and the sample standard deviation of the height. b. Find the sample mean and the sample standard deviation of the weight. c. Construct and interpret a confidence interval to estimate the mean height. d. Construct and interpret a confidence interval to estimate the mean weight. 3) (CLO 2) Test a claim that the mean height of people you know is not equal to 64 inches using the…
