Question

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

Answer 1

Construction of hypothesis

H₀ : p = 0.70

H₁ : p ≠ 0.70

Explanation:

A the given statement does not give how much the goal was

lets suppose "getting rich" was an important personal goal than the proportion was 70 %

suppose that we believe that proportion has changed then construction of hypothesis for this H₀ for null hypothesis and H₁ is alternative hypothesis

Construction of hypothesis

H₀ : p = 0.70

H₁ : p ≠ 0.70

So construction of hypothesis state null and alternative hypothesis.
