Adecade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 72% . suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. state the null hypothesis and the alternative hypothesis that we would use for this test.

Step-by-step explanation:

Given :  A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 72% .

Let 'p' be the new proportion of high school seniors who felt that "getting rich" was an important personal goal .

Claim :

We know that the null hypothesis has equal sign.

Therefore , the null hypothesis for the given situation will be opposite to the given claim will be :-

And the alternative hypothesis must be :-

Hence,  the null hypothesis and the alternative hypothesis that we would use for this test :
