A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was
66%
. 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
H0
and the alternative hypothesis
H1
that we would use for this test.
Homework Answers
SOLUTION:-
Here, we have to determine the null and alternative hypothesis:-
H0 : p=66% =66/100= 0.66
Ha : p not= 66% =66/100 0.66 for two tailed test
Where,
H0 is the null hypothesis.
Ha is the alternative hypothesis.

A decade-old study found that the proportion, p, of high school seniors who believed that "getting rich" was an important personal goal was 75%. A researcher decides to test whether or not that percentage still stands. He finds that, among the 225 high school seniors in his random sample, 175 believe that "getting rich" is an important goal. Can he conclude, at the 0.1 level of significance, that the proportion has indeed changed? Perform a two-tailed test. Then fill in...
