A group of 25 husbands and wives were chosen randomly. Each person was asked to indicate the most he or she would be willing to pay for a new car (assuming each had decided to buy a new car). The results are shown in the file P09_71.xlsx. Can you accept the alternative hypothesis that the husbands are willing to spend more, on average, than the wives at the 5% significance level? What is the associated p-value? Is it appropriate to use a paired-sample or independent-sample test? Does it make a difference? Explain your reasoning.
