Question
For number 17 to 20
A medical researcher says that less than 40% of Filipinos are smokers. In a random
sample of 200 Filipinos, 33.5% says that they are smokers. At 0.05 level of significance, is
there enough evidence to reject the researcher's claim?
17. Which of the following is the correct pair hypothesis?
a. Ho:p = 0.4 and H,:p # 0.4
b. Ho:p 2 0.4 and Hạ:p < 0.4
C. Ho:p = 0.335 and H;:p # 0.335
d. Ho:p 2 0.335 and H;:p < 0.335
18. What is the value of test statistic?
a. te = 1.88
b. te = -1.88
C. z = 1.88
d. ze = -1.88
19. Which of the following is the correct decision to take?
a. reject null, there is enough evidence to support the researchers claim
b. reject null, there is not enough evidence to support the researchers claim
c. fail to reject null, there is enough evidence to support the researchers claim
d. fail to reject null, there is not enough evidence to support the researchers claim
20. Which of the following is the correct decision to take given that the level of significance is
change to 0.01?
a. reject null, there is enough evidence to support the researchers claim
b. reject null, there is not enough evidence to support the researchers claim
c. fail to reject null, there is enough evidence to support the researchers claim
d. fail to reject null, there is not enough evidence to support the researchers claim
