The available options are:

(A)0.25

(B)0.78

(C)1.09

(D)2.25

(E)2.41​

Answer:

(B)0.78

Explanation:

Given the fact that percentile rank is usually between 0 to 100. Hence, considering the available options, the 100th percentile would be converted to 1.0 when representing the percentile into decimal places.

Since it is logically and mathematically impossible to go beyond the 100th percentile, hence, the option C, D, and E are wrong.

Also, since Sharon hoped to get a score well enough compared to her peers, then the correct answer is 0.78 which can be translated to 78 percentile. Because 0.78 is a better score than 0.25 or 78 percentile is better than 25 percentile because 78 percentile means she scored better than 78 percent of all the test takers.

Hence, the right answer is in this case is 0.78
