denis23 [38]

Answer:

The null hypothesis is H_0: p \geq 0.32

The alternative hypothesis is H_1: p < 0.32

Step-by-step explanation:

State the null and alternative hypotheses to test that less than 32% of mall visitors make a purchase

At the null hypothesis, we test if the proportion is of at least 32%, that is:

H_0: p \geq 0.32

We are testing if less than 32% of visitors make a purchase, so, at the alternative hypothesis, we test if the proportion is less than 32%, that is:

H_1: p < 0.32
