Background information: Allison collected additional days of data to monitor the process. 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. You do not need to include the units (minutes), ONLY the numeric value. USE EXCELL DATA TO GET…

The accompanying data were compiled by the admissions office of a certain college during the past 5 years. The data relate the number of college brochures and follow-up letters (x) sent to a preselected list of high school juniors who took the PSAT and the number of completed applications (y) received from these students (both measured in thousands). Brochures Sent, x     1.1     2     3.8     5     6.2 Applications Completed, y     0.3     0.5     1     1.25     1.6 (a) Derive an equation of the straight line that passes through the points (2, 0.5) and (5, 1.25).y =        (b) Use this equation to predict the number of completed applications that might be expected if 8000 brochures and follow-up letters are sent out during the next year. applications

Create scatterplot using Excel with the following variables: gender: 0 = male, 1 = female. height: in inches. weight: in pounds. First we will create a scatterplot to examine how weight is related to height, ignoring gender. To do that in Excel: Sort the data by gender: Hold down the Control key (Command key on MacOS) and click the A key to select all of the data in the worksheet. Select the Home tab, then the Editing group Sort & Filter -> Custom Sort. In the pop-up window, make sure that My list has headers box is checked and then choose gender from the pull-down menu next to Sort by. Click OK. Now select all of the data in columns B and C, select the Insert tab and in the Charts group choose Scatter. Choose the first scatterplot option (Scatter with only Markers). Now we have a scatterplot, but the data is all on the right of the plot. To fix this: Right-click on the x-axis, and choose Format Axis from the pop-up menu. Make sure that Axis Options is selected on the left, and…
