Question

I need help with all these answers points worth it

Answer 1

Explanation:

Mean is the sum of all values divided by the total number of values

Median is the value in the middle of a data set

(the median is the middle value when the data set is an odd number, or the arithmetic mean of the two medians when the data set is an even number)

Mode is the most frequent value

Range is the difference between the highest and the lowest values in a data set

.

1. Mean:

`(3 + 0 + 0 + 2 + 0 + 3 + 0 + 2 + 2 + 2 + 3 + 3)/(12) = 1 (2)/(3)`

Median: The data set is an even number (12)

The middle values are 3 and 0

`(3 + 0)/(2) = 1.5`

Modes: 2 and 3

Range: The highest value is 3 and the lowest is 0

`3 - 0 = 3`

.

2. Mean:

`(40 + 61 +95 + 79 + 9 +50 + 80 + 63 + 109 + 42 )/(10) = 62.8`

Median: The data set is an even number (10)

The middle values are 5 and 6

`(5 + 6)/(2) = (11)/(2) = 5.5`

Mode: There is no mode

Range: The highest value is 109 and the lowest is 9

`109 - 9 = 100`

.

3. Mean:

`(90 + 50 + 70 + 80 + 70 +60 + 20 + 30 + 80 + 90 + 20)/(11) = 60`

Median:The data set is an odd number (11)

The middle value is 6

Modes: 20, 70, 80, 90

Range: The highest value is 90 and the lowest is 20

`90 - 20 = 70`

.

4. Mean:

`(98 + 100 +65 + 78 +98 + 35 + 100 + 45 + 50 )/(9) = 74 (1)/(3)`

Median: The data set is an odd number (9)

The middle value is 98

Modes: 100 and 98

Range: The highest value is 100 and the lowest is 35

`100 - 35 = 65`

.

5. Mean:

`(8 + 2 + 9 +4 + 2 +7 + 8 + 0 + 4 + 1)/(10) = 4.5`

Median: The data set is an even number (10)

The middle values are 2 and 7

`(2 + 7)/(2) = 4.5`

Modes: 2, 4, 8

Range: The highest value is 9 and the lowest is 0

`9 - 0 = 9`

.

6. Mean: 22 1/15

Median: The data set is an even number (30)

The middle values are 21 and 23

The median is (21 + 23) / 2 = 22

Mode: 24 and 32

Range: The highest value is 40 and the lowest is 6

40 - 6 = 34
