The data set below has a lower quartile of 13 and an upper quartile of 37.

Levart [38]

The dataset 78 is an outlier of the dataset

<h3>How to determine the true statement about the outlier?</h3>

The dataset is given as:

1, 12, 13, 15, 18, 20, 35, 37, 40, 78

Where

Q1 = 13

Q3 = 37

The boundaries of the outliers are given as:

L = Q1 - 1.5 * (Q3 - Q1)

U = Q3 + 1.5 * (Q3 - Q1)

Substitute the known values in the above equation

L = 13 - 1.5 * (37 - 13) = -23

U = 37 + 1.5 * (37 - 13) = 73

This means that the data elements outside the range -23 to 73 are outliers.

78 is outside this range

Hence, 78 is an outlier of the dataset

Jenny wants a total of 12 barbie dolls by the time she is 9 years old. Right now she has 4 barbie dolls. How many more does she

Aleks04 [339]

Answer:

8 Barbie dolls.

Step-by-step explanation:

For this you can make a equation with addition.

4+x=12

Subtract 4 on both sides:

4-4+x=12-4

x=8

So, she needs 8 barbie dolls.
