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 below $Q_3$ 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.

The theater director recorded the number of seats occupied at past performances and the total revenue per

Norma-Jean [14]

Answer:

$45 (with the assumption made below)

Step-by-step explanation:

The equation is garbled; thus, to explain you I will assume the equation is

R(s) = -325 + 14s

Where:

R(s) is the revenue in dollars, as a function of the number of seats occupied.
s is the variable that represents the number of seast occupied
14 is the rate of change of the revenue per seat occupied (the price of a ticket).
-325 is the fixed cost of the theater for a performance (the amount of money the theater will lose if none seat is occupied).

Thus, you can predict the revenue when 70 seats are occupied by substituting s with 70.

R(70) = -325 + 14(70)

R(70) = -325 + 980 = $655

The residual value from a prediction is equal to the real value (observed value) less the preducted value:

Residual = real revenue - predicted revenue

Residual = $700 - $655 = $45
