Mathematically verify the outlier(s) in the data set using the 1.5 rule.

statuscvo [17]

Given:

The data values are:

7, 8, 11, 13, 14, 14, 14, 15, 16, 16, 18, 19

To find:

The outliers of the given data set.

Solution:

We have,

7, 8, 11, 13, 14, 14, 14, 15, 16, 16, 18, 19

Divide the data set in two equal parts.

(7, 8, 11, 13, 14, 14), (14, 15, 16, 16, 18, 19)

Divide each parenthesis in two equal parts.

(7, 8, 11), (13, 14, 14), (14, 15, 16), (16, 18, 19)

Now,

$Q_1=\dfrac{11+13}{2}$

$Q_1=\dfrac{24}{2}$

$Q_1=12$

And

$Q_3=\dfrac{16+16}{2}$

$Q_3=\dfrac{32}{2}$

$Q_3=16$

The interquartile range is:

$IQR=Q_3-Q_1$

$IQR=16-12$

$IQR=4$

The data values lies outside the interval $[Q_1-1.5IQR,Q_3+1.5IQR]$ are known as outliers.

$[Q_1-1.5IQR,Q_3+1.5IQR]=[12-1.5(4),16+1.5(4)]$

$[Q_1-1.5IQR,Q_3+1.5IQR]=[12-6,16+6]$

$[Q_1-1.5IQR,Q_3+1.5IQR]=[6,22]$

All the data values lie in the interval [6,22]. So, there are no outliers.

Hence, the correct option is 4.

The distance from your house to the park is represented by the expression "5x + 4 more than 2 − 2x." The distance from the park

Neko [114]

Answer:

The distance from the house to the school is equal to $(4x-2)$

Step-by-step explanation:

Let

A-----> the distance from house to the park

B----> the distance from the park to the school

C----> the distance from house to the school

so

$C=A+B$

we know that

$A=(2-2x)+(5x+4)$

$B=(3x-10)-(2x-2)$

so

Find the the value of C

$C=(2-2x)+(5x+4)+(3x-10)-(2x-2)$

$C=(4x-2)$

therefore

The distance from the house to the school is equal to $(4x-2)$

Ariana buys an ant farm from a store near her home. the ant farm price $12, and the sales tax is 7% what is the total price of t

aalyn [17]

Answer:

The total price for ant farm is $12.84

Step-by-step explanation:

The price of ant farm = $ 12

The sales tax on the price = 7%

Noe, 7% of $12 = $\frac{7}{100} \times 12 = 0.84$

⇒The tax amount on the price = $0.84

So, the Taxed amount = The original price + Tax

$ 12 + $0.84 = $12.84

Hence the total price for ant farm is $12.84
