2. In a sample of 74 adults selected randomly from one town, it is found that 9 of them have been exposed to a particular strain of the flu. Using P-value, test the claim that the population proportion of all adults in the town that have been exposed to this strain of the flu is greater than 0.10. Use a 0.01 significance level and determine conclusion.

a. P-val = 0.732, reject the alternative hypothesis

b. P-val = 0.535, reject the alternative hypothesis

c. P-val = 0.268, fail to reject the null hypothesis

d. P-val = 0.732, fail to reject the alternative hypothesis

e. P-val = 0.535, fail to reject the null hypothesis

f. P-val = 0.268, reject the null hypothesis

Answer 1

from above correct option is :

c. P-val = 0.268, fail to reject the null hypothesis
