Regis University Operations And Supply Chain Management Assignment Help - strong correlation

Question - In many fast food restaurants, there is a strong correlation between a menu item's fat content
(measured in grams) and its calorie content. We want to investigate this relationship. Using all of the
food menu items at a well-known fast food restaurant, the fat content and calorie contents were
measured. We decide to fit the least-squares regression line to the data, with fat content(x) as the
explanatory variable and calories (y)as the response variable. A scatterplot of the data (with
regression line included), and a summary of the data are provided. One of the menu items is a
hamburger with 107 grams of fat and 1410 calories.

r = 0.979 (correlation between x and y)
= 40.35 (mean of the values of x)
= 662.88 calories (mean of ...Read More the values of y)
= 27.99 grams (standard deviation of the values of x)
= 324.90 calories (standard deviation of the values of y)
The slope of the least-squares regression line is

A. –11.36.
B. 11.36.
C. 0.979.
D. 16.08. ...Read Less
