Question

A spouse stated that the average amount of money spent on Christmas gifts for immediate family members is above $1200.The correct set of hypotheses is: A) H₀:= 200,H₁:< 1200 B) H₀:> 1200,H₁:= 1200 C) H₀:= 1200,H₁:> 1200 D) H₀:< 1200,H₁:= 1200

Quizplus · Accepted Answer

The null hypothesis (H0) should reflect the opposite of what the spouse stated, which is that the average amount of money spent on Christmas gifts for immediate family members is not above $1200. Therefore, H₀:= 1200 is the correct null hypothesis. The alternative hypothesis (Ha) should reflect the spouse's claim that the average is above $1200. Therefore, H₁:> 1200 is the correct alternative hypothesis. Choice C reflects these correct hypotheses.
