Sagot :
The only conclusion that is supported by the interval is; C. There is evidence to conclude that p1>p2 because all values in the interval are positive.
What is the confidence Interval?
We are given a confidence interval for the difference in proportions. The null hypothesis means that there's no difference. Thus;
H0 = p1 - p2 = 0
However, If the difference is positive, it means that we have sufficient evidence as p1 > p2 but If it's negative, then we have sufficient evidence as p2 > p1.
Option A: This is incorrect because of interpretation of the interval.
Option B & D: They are not correct because they are incomplete
Option E: This is not correct because it did not properly get the definition of alpha-level and p-value with confidence interval values.
Thus, only option C is correct.
The missing options are;
A. There is evidence to conclude that p1>p2 because 0.325 is greater than 0.247.
B. There is evidence to conclude that p1
C. There is evidence to conclude that p1>p2 because all values in the interval are positive.
D. There is evidence to conclude that p1
E. There is evidence to conclude that p2>p1 because 0.247 and 0.325 are both greater than 0.05.
