    (a) Null hypothesis: The new drug reduces the rate of first heart attacks by a percentage same as aspirin.

    (b) Alternate hypothesis: The new drug reduces the rate of first heart attacks by a percentage greater than aspirin.

    Step-by-step explanation:

    (a) A null hypothesis is a statement from the population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.

    (b) An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
