Answer:

A) 8.5 miles per gallon

Step-by-step explanation:

Given

$x = \{12\ 13\ 15\ 16\ 16\ 17\ 18\ 18\ 19\ 19\ 20\ 20\ 22\ 23\ 24\ 26\ 26\ 27\ 27\ 29\}$

$n = 20$

Required

The IQR

This is calculated as:

$IQR = Q_3 - Q_1$

Calculate $Q_1$

$Q_1 = \frac{1}{4}(n + 1)th$

$Q_1 = \frac{1}{4}(20 + 1)th$

$Q_1 = \frac{1}{4}(21)th$

Remove bracket

$Q_1 = 5.25th$

This means that:

$Q_1$ is the mean of 5th and 6th item

From the given data:

$5th \to 16$

$6th \to 17$

So, we have:

$Q_1 = \frac{1}{2}(16 + 17)$

$Q_1 = \frac{1}{2}(33)$

$Q_1 = 16.5$

$Q_1 = 16.25$

Calculate $Q_3$

$Q_3 = \frac{3}{4}(n + 1)th$

$Q_3 = \frac{3}{4}(20 + 1)th$

$Q_3 = \frac{3}{4}(21)th$

Remove bracket

$Q_3 = 15.75th$

This means that:

$Q_3$ is the mean of 15th and 16th item

From the data:

$15th \to 24$

$16th \to 26$

So:

$Q_3 = \frac{1}{2}(24 + 26)$

$Q_3 = \frac{1}{2}(50)$

$Q_3 = 25$

Recall that:

$IQR = Q_3 - Q_1$

$IQR = 25 -16.5$

$IQR = 8.5$

If x represents the number of years since 2000 and y represents the gas price, predict what the difference between the gas price

natali 33 [55]

The difference between the gas prices in 2013 and 2001 is 3.00

<h3>The linear equation of the graph </h3>

Start by calculating the slope of the line of best fit using:

$m = \frac{y_2 -y_1}{x_2 - x_1}$

From the line of best fit, we have:

$m = \frac{3 - 2}{8 - 4}$

$m = \frac{1}{4}$

The regression equation is then represented as:

$y = m(x -x_1) + b$

So, we have:

$y = \frac 14(x -4) + 2$

$y = \frac 14x -1 + 2$

$y = \frac 14x +1$

Express as decimals

$y = 0.25x +1$

<h3>The price of the gas</h3>

In 2001, the value of x is 1

So, we have:

$y = 0.25(1) +1 =1.25$

In 2013, the value of x is 13.

So, we have:

$y = 0.25(13) +1 =4.25$

So, the difference (d) between the prices is:

$d = 4.25 - 1.25$

$d = 3.00$

Hence, the difference between the gas prices in 2013 and 2001 is 3.00
