Question

A data set contains information on the grams of fat and number of calories in 28 different fast foods. The correlation coefficient between fat content and calories is determined to be 0.02. Calculate the p-value for the two-tailed test of significance.

Answer 1

Using a calculator, it is found that for the two-tailed test of significance, the p-value is of 0.9195.

The correlation coefficient is also called Pearson's r-score, and is used for two-tailed tests. To find the p-value, the information needed is:

• The value of the Pearson's r-score, that is, the value of the correlation coefficients.
• The sample size.

In this problem, we have that the correlation coefficient is of r = 0.02, with a sample size of n = 28.

• Using it as the input for a r-score calculator, the p-value is of 0.9195.
