A U.S. government report stated that, With bank interest rates around

1.0%, 8% of wage earners believe it worthwhile to keep money in a

savings account. However, at 3.0% interest, 36% of wage earners believe

it worthwhile to keep money in a savings account. The margin of error

for both studies is 4 percentage points.. A proper conclusion from the

studies is that:

A. increasing the interest rate from 1% to 3% will increase the number of persons saving money in a savings account.

B. increasing the interest rate may well have no effect on the number of persons saving money in a savings account.

C. increasing the interest rate will increase the number of persons saving money in a savings account.

D. the interest rate difference between 1% and 3% may well have no effect on the number of persons saving money in a savings account.
