Question

You are the manager at a grocery store, and about to receive a shipment of pineapples. If more then 25% of the pineapples are rotting, then you are supposed to reject the delivery. Write the appropriate null and alternate hypotheses for this situation.

Answer 1

Explanation:

The null hypothesis is the hypothesis to be tested. From the statement given, the null hypothesis would be expressed as

More than 25% of of the pineapples are rotting.

The alternative hypothesis is a statement of what is believed to be true if our sample data causes us to reject the null hypothesis. Therefore, the alternative hypothesis would be expressed as

Less than 25% of of the pineapples are rotting.
