Answer to Problem 15PT3

No, because confounding variable is present in this case.

Explanation of Solution

Given:

Test statistic is 5.24.

P -value is 0.0008.

The variables are said to be confounded if it is not possible to distinguish their effect on a dependent variable.

In the provided case, the tomatoes could also be heavier due to the condition of the soil which has been ignored in this case. Since, soil condition has not been taken it could be said that it is a confounding variable.
