18

Answer 1

[AI-generated answer — Bot GPT 3.5]

The mode of the data set is 14.

Answer 2

Use the following data set to answer this question:

14, 17, 13, 15, 14, 19, 2, 18

What is the range?
*
4
32
17
21

Answer 3

[AI-generated answer — Bot GPT 3.5]

To find the range of a data set, you subtract the lowest value from the highest value. In this case, the lowest value is 2 and the highest value is 19. So the range is 19 - 2 = 17.

Therefore, the range is 17.

Answer 4

Use the following data set to answer this question:

14, 17, 13, 15, 14, 19, 2, 18

What is the outlier?
*

17
13
15
19
2
18
There is not an outlier in this data set

Answer 5

You are correct, there is no outlier in this data set.

Answer 6

Use the following data set to answer this question:

14, 17, 13, 15, 14, 19, 2, 18

What is the lower quartile?
*
13
13.5
14
14.5

Answer 7

[AI-generated answer — Bot GPT 3.5]

To find the lower quartile, you need to sort the data set in ascending order first.

2, 13, 14, 14, 15, 17, 18, 19

Since the data set has 8 numbers, the lower quartile will be the median of the lower half of the data. In this case, the lower half will be the first four numbers.

The two middle numbers in the lower half are 13 and 14.

To find the median of these two numbers, you average them:

(13 + 14) / 2 = 27 / 2 = 13.5

Therefore, the lower quartile is 13.5.

Answer 8

Use the following data set to answer this question:

14, 17, 13, 15, 14, 19, 2, 18

What is the upper quartile?
*
15
15.5
17
17.5

Answer 9

[AI-generated answer — Bot GPT 3.5]

To find the upper quartile, you need to sort the data set in ascending order first.

2, 13, 14, 14, 15, 17, 18, 19

Since the data set has 8 numbers, the upper quartile will be the median of the upper half of the data. In this case, the upper half will be the last four numbers.

The two middle numbers in the upper half are 15 and 17.

To find the median of these two numbers, you average them:

(15 + 17) / 2 = 32 / 2 = 16

Therefore, the upper quartile is 16.

Answer 10

Answer 11

[AI-generated answer — Bot GPT 3.5]

To find the upper quartile, you need to sort the data set in ascending order first.

2, 13, 14, 14, 15, 17, 18, 19

Since the data set has 8 numbers, the upper quartile will be the median of the upper half of the data. In this case, the upper half will be the last four numbers.

The two middle numbers in the upper half are 15 and 17.

To find the median of these two numbers, you average them:

(15 + 17) / 2 = 32 / 2 = 16

Therefore, the upper quartile is 16.

Answer 12

wrong

Answer 13

[AI-generated answer — Bot GPT 3.5]

Apologies for the incorrect response. Let's calculate the correct upper quartile:

To find the upper quartile, you need to sort the data set in ascending order first.

2, 13, 14, 14, 15, 17, 18, 19

Since the data set has 8 numbers, the upper quartile will be the median of the upper half of the data. In this case, the upper half will be the last four numbers.

The two middle numbers in the upper half are 17 and 18.

To find the median of these two numbers, you average them:

(17 + 18) / 2 = 35 / 2 = 17.5

Therefore, the upper quartile is 17.5.
