2. A study was conducted to see if daily exercise is effect manager at a large retail store selected a random sample of 30 cmployces. Fifteen of the employees were randomly sclected to exercise cach day and the other fifteen did not excrcise. The blood pressure of the employees was measured before the study and again after 3 months. The results showed that people that exercise daily had, on average, significantly lower blood pressure than the pcople in the non-exercise group. Based on the design of the study, which of the following is true The results can be generalized to the entire store and we can coadude that excrcising causes lower blood pressurc. a. b. The results cannot be generalized to the entire store, but we can conclude that exercising causes lower blood pressure. c. The results can be generalized to the entire store, but we cannot conclude that exercising causes lower blood pressure. d. The results cannot be generalized to the entire store and we cannot conclude that exercising causes lower blood pressure.

![12. A study was conducted to see if daily exercise is effective at lowering blood pressure. To test this, a
manager at a large retail store selccted a random sample of 30 employces. Fifteen of the employees were
randomly sclected to exercise each day and the other fifteen did not excrcise. The blood pressure of the
employees was measured before the study and again after 3 months. The results showed that people that
exercise daily had, on average, significantly lower blood pressure than the pcople in the non-exercise
group. Based on the design of the study, which of the following is true
The results can be generalized to the entire store and we can condude that excrcising
causes lower blood pressurc.
b. The results cannot be generalized to the entire store, but we can conclude that
exercising causes lower blood pressure.
The results can be generalized to the entire store, but we cannot conclude that
exercising causcs lower blood pressure.
The results cannot be generalized to the entire store and we cannot conclude that
