Suppose 300 nursing students took a certification test that is worth 100 points. The five-number summary for the scores is shown here:

Minimum = 40; Q1 = 65; Median = 82; Q3 = 88; Maximum = 100

About how many students scored 65 or better?

About how many students scored 88 or better?

225 students scored 65 or better and 75 students scored 88 or better.

Step-by-step explanation:

We are given that The five-number summary for the scores of 300 nursing students are given :

Minimum = 40

Median = 82

Maximum = 100

is the first quartile and is the median of the lower half of the data set. 25% of the numbers in the data set lie below and about 75% lie above .

is the third quartile and is the median of the upper half of the data set. 75% of the numbers in the data set lie below and about 25% lie above

i) .About how many students scored 65 or better?

Since we know that 75% lie above .

So, Number of students  scored 65 or better =

ii)About how many students scored 88 or better?

Since we know that 25% lie above

So, Number of students scored 88 or better =

Hence 225 students scored 65 or better and 75 students scored 88 or better.
