**Null and alternative hypothesis:**

*Null Hypothesis:*

*Alternative Hypothesis:*

An alternative hypothesis is a contradictory statement of null hypothesis. It can be denoted as* H _{a}*.

Step 2

**a. Stating the appropriate null and alternative hypotheses:**

The importer is planning package a new booklet only if it helps the customers more than the current booklet. It was found that only 30% of the customers were able to program their DVD player. The experiment found that 16 out of the 60 customers were able to programme their DVD player.

Let *p* be the proportion of customers who were able to programme their DVD player.

The hypotheses are given below:

*Null hypothesis:*

*H*_{0} : *p* = 0.30.

That is, the proportion of customers who were able to programme their DVD player is 0.30.

*Alternative hypothesis:*

*H*_{a} : *p* > 0.30.

That is, the proportion of customers who were able to programme their DVD player is greater than 0.30.

Step 3

**b. Finding the p-value for the hypothesis test:**

*Test statistic:*

The test statistic f...
