15, 17, 18, 12, 17, 18, 13, 13, 19, 21, 19, 15, 16, 15, 15, 16

Answer 1

Wait til I ask you questions.

Answer 2

List the data set from least to greatest. Separate values with a comma. Be careful with extra spacing!

Answer 3

Find the following statistics of the data set:

Mean:
Meridian:
Mode:
Range:

Answer 4

Mean is NOT 16.

Answer 5

Create a line plot that represents your data set. (Above the number line, put X's in boxes to show numbers in the data set [One for each box. Leave blank if that number isn't on the data set].)

Answer 6

Count how many numbers in the data set belong to each interval in the table below. Put this number in the "frequency" column. If there are no numbers in the interval, be sure to type 0.

Interval:
12-13
14-15
16-17
18-19
20-21

Frequency:
???
???
???
???
???

Answer 7

The actual frequency numbers were: 3, 4, 4, 4, 1.

My apologies, please ask me your questions and I will provide the answers.

Answer 10

Sure thing! Here is the data set sorted from least to greatest:

12, 13, 13, 15, 15, 15, 15, 16, 16, 17, 17, 18, 18, 19, 19, 21

Answer 11

Sure thing! Here are the statistics of the data set:

Mean: 16
Median: 16
Mode: 15
Range: 9

Answer 12

I apologize for the mistake. I recalculated the mean and got an answer of 16.1875.

Answer 13

Here is a line plot that represents the data set:

```
X
X X X
X X X
X X X
X X X X X X
12 13 14 15 16 17 18 19 20 21
```
(Note: In this line plot, there are three X's above each value from 12 to 16 to represent the frequency of those values in the data set. The X's above 17 and 18 have a frequency of two, while the X above 19 has a frequency of two.)

Answer 14

Sure thing! Here are the frequencies for each interval:

Interval: 12-13, 14-15, 16-17, 18-19, 20-21

Frequency: 2, 5, 5, 2, 2

(Note: Two numbers in the data set, 12 and 13, belong to the 12-13 interval. Five numbers each belong to the 14-15 and 16-17 intervals. Two numbers each belong to the 18-19 and 20-21 intervals.)

Answer 15

Thank you for letting me know. My apologies for the mistake. The actual frequencies for each interval are as follows:

Interval: 12-13, 14-15, 16-17, 18-19, 20-21

Frequency: 3, 4, 4, 4, 1
