The error is that the graph is moving up two and over one. Basically using the slop 2/1 instead of 1/2. The slope is rise/run, so it should rise up 1 unit and run 2 units to the right.

Suppose 300 nursing students took a certification test that is worth 100 points.
Alja [10]

Answer:

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

Q_1 = 65

Median = 82

Q_3 = 88

Maximum = 100

Q_1 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 Q_1 and about 75% lie above Q_1 .

Q_3 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 belowQ_3 and about 25% lie above Q_3

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

Q_1 = 65

Since we know that 75% lie above Q_1 .

So, Number of students  scored 65 or better = 75\% \times 300 = \frac{75}{100} \times 300 =225

ii)About how many students scored 88 or better?

Q_3 = 88

Since we know that 25% lie above Q_3

So, Number of students scored 88 or better = 25\% \times 300 = \frac{25}{100} \times 300 =75

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