The null hypothesis (H0) should always contain an equality sign, in this case, it is that the average amount spent on Christmas gifts for immediate family members is equal to $1,200. The alternative hypothesis (Ha) should contain the inequality sign representing the claim of the spouse, in this case, it is that the average amount spent on Christmas gifts for immediate family members is above $1,200. Therefore the correct set of hypotheses is H₀: F1F1F1S1μF1F1F10 F1F1F1S1=F1F1F10 1200 vs. H₁: F1F1F1S1μF1F1F10 F1F1F1S1>F1F1F10 1200. Choice C meets these requirements.
