A production supervisor wishes to find the relationship between the number of workers on a job and the number of units produced for a shift for a sample of 8 days (see data below). The standard deviation of the workers is 3.66 & the standard deviation of the units produced is 3.16. A. Find the correlation coefficient and explain it briefly (3 words). B. Find the coefficient of determination & write a statement explaining it. C. Find the regression equation and write it out (hint: get the slope and intercept). D. Predict the number of units produced if 10 employees are working the shift today. Workers Units 9 23 3 17 5 19 7 19 12 22 6 16 13 24 4 16

The production department of Celltronics International wants to explore the relationship between the number of employees who assemble a subassembly and the number produced. As an experiment, 2 employees were assigned to assemble the subassemblies. They produced 13 during a one-hour period. Then 4 employees assembled them. They produced 22 during a one-hour period. The complete set of paired observations follows. Number of Assemblers One-Hour Production (units) 2 14 4 20 1 7 5 23 3 16 The dependent variable is production; that is, it is assumed that different levels of production result from a different number of employees. Please answer questions a to d. Please show all steps of derivation. a. Please calculate the sample mean and standard deviation of the number of assemblers and production, respectively. b. Please calculate the correlation coefficient of the number of assemblers and production. c. Please estimate the "a" and "b" in the following equation based on the data above. d. What is the coefficient of determination of the estimated equation in c? What does this value mean intuitively?

An assembly plant tracks the daily productivity of the workers on the line. Each day, for every employee, the plant records the number of hours put in (Hours) and the number of completed packages assembled by the employee (Count). A scatterplot of the data for one day shows a linear trend. A fitted line with the equation Estimated Count = -2 + 15 Hours summarizes this trend. (a) Interpret the slope and intercept in the fitted line. (b) A carton holds 12 packages. A working day at this plant has 8 hours. Describe the regression line if the data were converted to cartons produced (Y) and days (or fraction of a day) worked. (c) Would the r^2 summary attached to the regression model change along with the slope and intercept when the data are converted to cartons and days? (d) What about the value of se? Would it change with the new scales?
