According to some researched data, a sample of 45 male customers (group 1) who shopped at a supermarket showed that they spend an average of $93 with a standard deviation of $11. Another sample of 50 female (group 2) customers who shopped at a supermarket showed that they spend an average of $84 with a standard deviation of 16. Using the 10% significance level, can you conclude that the claim that the mean amount spent by all male customers is not different than female customers? 1. H0 hypothesis: A. 1 2 µ µ− ≠ 0 B. 1 2 µ µ− = 0 C. 1 2 µ µ− ≤ 0 D. 1 2 µ µ− ≥ 0 2. Critical value: A. ±1.28 B. 1.28 C. 1.645 D. ±1.645 3. Test statistics: A. 3.22 B. −1.58 C. −3.22 D. 1.58 4. Conclusion: A. Accept that the mean amount spent by all male customers is not different than female customers? B. Reject that the mean amount spent by all male customers is not different than female customers? 5. Comment: A. Accept that the mean amount spent by all male customers is not different than female customers? B. Reject that the mean amount spent by all male customers is not different than female customers?
