Number 21, please. Thank you

For numbers 18 to 21: A study was conducted using 50 undergraduates at a large private university who volunteered to participate in the research as partial fulfillment of a course requirement. One of the items studi ed was the maximum daly amount of alcohol consumed in the last month. Base on the datain the following table, are there differen ces between males and females in the maximum amount of alcohol consumedin any one day in the past month? Use 5%level of significance. Assume equal variances. Alcohol consumed Mean Male 8.2 female 5.6 5.7 Standard deviation Number of students 5.9 20 30 18. Which of thefollowing is the appropriate altemative hypothesis? A There are more female participants than males B. The amount of alcohol consumed by males is higherthan the amount consumed by the females. C The amount of alcohol consumed by males and females in the past month is not the same. D. The amount of alcohol consumed by males and females in the past month is the same. 19. The pooled variance would be? A 3456 C 33.408 D. 5.780 B. 6.73 20. What is the value of the test statistics? B. 1.558 C 0.270 D. 3.733 A 1.980 21. With to.o2s=±2.011: what would be your decision? A Thereis no sufficient datato make a decision B. Failedto reject the null hypothesis C Reject the null hypothesis D. Either A or B
