Fat Grams and Secondary Schools. The number of fat calories and grams of saturated fat in a number of fast-food non-breakfast entrees are shown below.

Fat Calories 190 220 270 360 460 540
Sat. Fat 9 8 13 17 23 27

Compute the t statistics for testing the correlation between variables;

Null hypothesis H0: ρ = 0
Alternative hypothesis HA: ρ ≠ 0 or HA: ρ < 0 or HA: ρ > 0

Second, we calculate the value of the test statistic using the following formula:

Test statistic: t statistics = r (√ n−2 )/ (√ 1−r 2 )
