What is the relationship between the amount of fat and the n

What is the relationship between the amount of fat and the number of calories in a candy bar? Researchers obtained samples of 75 candy bars and measured the number of grams of fat and the number of calories in each bar. A linear-regression model will be fit to the data using least squares. Here is some output from a computer package (with some information hidden).

RSquare 0.651355

RSquare Adj 0.646579

Root Sq Mean Error 36.85632

Mean of Response 243.0267

Term Estimate Std Error t Ratio Prob> |t|

Intercept 139.30267 9.848763 14.14 <.0001*

Total fat g 8.7348787 0.748046 11.68 <.0001*

Suppose the researchers test the hypotheses H0: the slope of the least-squares regression line = 0 Ha: the slope of the least-squares regression line 0 The value of the t statistic for this test is:

a)0.237

b)14.14.

c)11.68.

Solution

Answer : c. 11.68
The value of the t statistic for this test is: 11.68 Answer
