Possible Answers:

Find the GMAT score that corresponds to the 90th percentile Round to the nearest whole number

None of the other responses is correct.

Correct answer:

Explanation:

The stem-and-leaf display represents 53 scores. The "stems" (or left column) represent the tens digits, and the "leaves" in each row represent units digits, so the scores are

The student who scored an 86 outscored 42 of the students, or

of them. Since percentile is given to the nearest whole number, the correct response is 79.

Find the 85th percentile score in the following test results.

{95, 88, 70, 75, 83, 70, 66, 91, 68, 76, 82}

Correct answer:

Explanation:

{95, 88, 70, 75, 83, 70, 66, 91, 68, 76, 82}

Arrange the values in numerical order.

{66, 68, 70, 70, 75, 76, 82, 83, 88, 91, 95}

Use the following to calculate percentile-

where  is the percentile and  is the number of data in the set

This number gives of the location of the 85th percentile in our ordered set. Since it is not a whole number, round up, which will give us 10.

The 85th percentile score is the 10th value in our set, which is 91.

If a student is ranked eight out of ten in a competition, what is the student's percentile rank?

Correct answer:

Explanation:

The formula to calculate a percentile rank is:  

where  represents total of scores below the rank, and  is the total number of competitors.

Substitute the values into the formula.

The times for a six-mile race are shown below.

Sean:     hours

Ankur:   hours

Sarah:   hours

Fred:     hours

Ron:      hours

Jareth:  hours

Determine which percentile Sean's time is in.

Correct answer:

Explanation:

First arrange the runners in order of fastest to slowest times:

Ron

Sarah

Jareth

Sean

Ankur

Fred 

There are six runners so there will be six different percentiles, each seperated by  percent. A person's percentile refers to which percentage of times are below that person's time. For example, Ron's time is better than  percent of all runners, so he is in the rd percentile.

Then each runner is in the following percentiles:

Ron - rd

Sarah - th

Jareth - th

Sean - rd

Ankur - th

Fred - th

As you can see, Sean is in the rd percentile.

In a litter of nine kittens, the only orange kitten weighs more than three in the litter, and less than the other remaining five. 

What is the percentile of the orange kitten's weight in comparison to the litter?

Correct answer:

Explanation:

The percentile is equal to how many items in the set are equal to or less than the one in question divided by the total number of items in the set.

Because there are four items equal to or less than the orange kitten's weight and there are nine items total in the set, the percentile is equal to

     or    

98, 99, 99, 100, 101, 102, 104, 104, 105, 105, 107, 110, 112, 112

For the above data set, 102 is in what percentile?

Explanation:

In the data set, 102 is the 6th data point listed. There are 14 data points total. This means that % of the data is at or below 102. That's approximately the 43rd percentile.

98, 99, 99, 100, 101, 102, 104, 104, 105, 105, 107, 110, 112, 112

For the above data set, 110 is in what percentile?

Explanation:

The number 110 is the 12th in the list of 14 data points. That means that %. Since about 86% of the data points are at or below 110, it's in the 86th percentile.

Above is the stem-and-leaf display for a group of test scores. Which of the following scores would come closest to being at the  percentile?

Correct answer:

Explanation:

The stem-and-leaf display represents 53 scores. The score at the 35th percentile would be the score that is greater than 35% of the scores, or

What is the probability that a randomly selected student will score 600 or above on the GMAT?

A score of 600 is one standard deviation above the mean, so it has a z value of 1.00. Using either a z table or the p–z converter, we find that the probability that a randomly selected z score in a normal distribution will exceed z = 1.00 is . 159, the right-tailed p value, or about 16%.
