A researcher wanted to predict the sodium content (in milligrams) of beef hot dogs by looking at the calorie content.  His findings from a sample of 10 beef hot dogs are summarized below. The regression equation for his data is          ŷ= -299.48 + 4.35 x    Calories  186  181  176  149  184  190  158  139  175  148  Sodium  495  477  425  322  482  587  370  322  479  375                                                                                 Interpret the slope in terms of this problem.  If appropriate, find the sodium content if the calorie content is 170. If not, why?  If appropriate, find the sodium content if the calorie content is 136. If not, why?

The file Galton on D2L contains the 928 observations Francis Galton used in 1885 to estimate the relationship between the heights of parents and the heights of their children. The column Children refers to the height (in inches) of a child, and the column Mid-Parents refers to the average height (in inches) of the mother and father of that child. You can download this file into Excel and Minitab. a. Calculate the regression Height of Children = a +b (Height of Mid-Parents). b. Calculate the average for Height of Children, and calculate the average Height of Mid-Parents. c. Create a new variable in Minitab which is the Height of Children measured in terms of deviations from its mean. Call this new variable y. Also, create a new variable in Minitab with is the Height of Mid-Parents measured in terms of deviations from its mean. Call this new variable x. Calculate the regression y = a + bx. You can create the new y and x variables in Excel of Minitab, whichever you find more convenient.…
