13) In a goodness-of-fit test where the sample size is 200, there are 5 categories, and the significance level is .05. The critical value of X2 is a. 9.488b. 11.070c. 43.773d. None of the above. 14) In a goodness-of-fit test 15) In a contingency table 16) In a contingency table a sample of 400 people is classified by gender and hair color (4 groups: blond, brown, black, and red). How many degrees of freedom are there? 17) For a X2 goodness-of-fit test a. There is only one degree of freedom.b. The rejection region is in the upper right tail.c. The scale of measurement is interval.d. We must assume a normal population. 18) To find the expected frequency in a contingency table
19) Suppose we select a sample of 100 observations and organize them into 6 categories. We wish to investigate whether the number of observations could be the same in each of the categories in the population. How many degrees of freedom are there? 20) Under what conditions could the X2 distribution assume negative values? 21) The philosophy of statistical quality control is to a. Inspect the quality into the product.b. Make it correct the first time.c. Develop an adversarial relationship with the production department.d. Shift costs from the manufacturing to the inspection department. 22) Dr. W. Edwards Deming 23) Chance variation is 24) A Pareto Charta. Was developed by Dr. Walter A. Shewhart of the Bell Laboratories in the 1920s. b. Is designed to show that 80 percent of the activity is caused by 20 percent of the factors. c. Is one of Deming?s 14 points. d. Highlights chance variation.
