Question: The paper “External Search Effort: An Investigation Across Several Product Categories'' (J. of Consumer Research (1987):83-91) reported on the results of a survey on buying habits.

For a sample of buyers of small TVs, the mean number of visits to retail stores prior to making a purchase was 2.29. Suppose that this mean was based on a sample of size 100 and that the sample standard deviation was 1.6. On the other hand, for a sample of buyers of large TVs, the mean number of retail visits was reported to be 3.25. Assuming the sample size was also 100 and that the sample standard deviation was 1.7.

Based on these results, would you conclude that buyers of large TVs make more retail visits, on the average, than buyers of small TVs? Explain your answer.
