Inspection records were reviewed for 630 units of a particular product, and the number of units that passed and failed inspection was determined based on three inspector experience levels. The results are shown in the following table. (Table is the picture) b. Calculate the value of the test statistic. (Round the intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.) Test Statistic = c.

- 1. A physician wanted to compare two types of pain relief. One is medication and the other is using pressure points. To test whether medication relieves pain faster, they have 10 migraine sufferers compare both types of pain relief and record their observations on a standardized scale. A coin flip was used to determine which type of headache relief each individual would try first. Results indicated that there was no difference in the two types of pain relief. Complete parts (a) through (f) below. (a)What type of experimental design is this? (b)What is the response variable in this study? (c)What is the factor that is set to predetermined levels?

Steps to monitor using the control charts: Now monitor the process. An additional ten days of data have been collected, see table labeled “1st 10 Days of Monitoring Reservation Processing Time” in the Data File. Develop Xbar and R charts for the 1st 10 days of monitoring. Plot the data for the 1st 10 days on the Xbar and R charts. Is the process in control? If the control chart indicates an out-of-control process, note which days, the pattern, and whether it is the Xbar or R chart. Now that we have set up the control charts using enough data from a stable process, the 30 days of data, we will monitor the process. While monitoring the process, what will we use as the upper control limit for the R (range) Chart to compare against our new range values? Enter your response to three decimal places.
