Quizplus · Accepted Answer

The null hypothesis states that the average amount spent on Christmas gifts for immediate family members is equal to $1200 (μ = 1200), while the alternative hypothesis states that the average amount spent is greater than $1200 (μ > 1200). This is the correct set of hypotheses for this scenario since the spouse is stating that the average amount spent is above $1200, indicating a one-tailed test for an increase in spending. Therefore, the correct choice is C.
