Question

a decade - old study found that the proportion of high school seniors who felt that “getting rich” was an important personal goal was 73%. 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 (h_0) and the alternative hypothesis (h_1) that we would use for this test.
(h_0:square)
(h_1:square)

Explanation:

Step1: Define null hypothesis

The null hypothesis $H_0$ assumes no change. So it is the proportion is the same as the old - study value.
$H_0: p = 0.73$

Step2: Define alternative hypothesis

The alternative hypothesis $H_1$ is that the proportion has changed. A change means it is either greater or less than the original proportion, so it is a two - tailed test.
$H_1: p
eq0.73$

Answer:

$H_0: p = 0.73$
$H_1: p
eq0.73$
