Suppose that you used a 9-point rating scale and that you wanted to compare men who had an annual income over $50,000 (group 1) with men who had an annual income less than or equal to $50,000 (group 2) on their liking of a new product. if you studied 40 men in group 1 and they have a mean of 7 and a standard deviation of 2.5, while the 35 men in group 2 have a mean of 5 and a standard deviation of 1.4, what is the approximate value of t using the t-test?
