Question 5 (2 points) A study is conducted to see the effectiveness of two COVlD-19 vaccines: A and B. Vaccine A works effectively on 205 people in a sample of 220. Vaccine B works effectively on 585 people out of a sample of 650. Does it appear that there is a significant difference in the effectiveness of these two vaccines? Conduct a hypothesis test at 5% level of significance. Hint: Please keep to three places past the decimal in determining proportions! What is your conclusion in the context of the problem? 0 A) We do not have enough information to make a conclusion. 0 B) We have evidence to show that vaccine B is significantly more effective than vaccine A. O C) We have evidence to show that vaccine A is significantly more effective than vaccine B. O D) We have sufficient evidence to suggest that vaccine A is significantly different from vaccine B. O E) We do not have enough evidence to show that vaccine A is significantly different from vaccine B.

Conduct a hypothesis test at 5% level of significance. Hint: Please keep to three places past the decimal in determining proportions! What is your decision and why? 0 A) Reject Ho since p-value > 0.05 O B) Do not reject Ho since p-value 0.05 O E) Reject Ho since p-value
