Below are the jersey numbers of 11 players randomly selected from a football team. Find the range, variance, and standard deviat

ion for the given sample data. What do the results tell us? 33 29 97 56 26 78 83 74 65 47 58 Range = (Round to one decimal place as needed.) Sample standard deviations ? = (Round to one decimal place as needed) Sample variance = (Round to one decimal place as needed) What do the results tell us? a. Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless. b. Jersey numbers on a football team vary much more than expected c. The sample standard deviation is too large in comparison to the range. d. Jersey numbers on a football team do not vary as much as expected.

Answer:

Range = 71

Variance = 546.0

Standard Deviation = 23.4

Option A) Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.

Step-by-step explanation:

We are given the following data set in the question:

33, 29, 97, 56, 26, 78, 83, 74, 65, 47, 58

Formula:

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}  

\text{Variance} = \displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}  

where x_i are data points, \bar{x} is the mean and n is the number of observations.  

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{646}{11} = 58.7

Sum of squares of differences = 5460.18

\text{Variance} = \frac{5460.18}{11} = 546.0

S.D = \sqrt{\frac{5460.18}{10}} = 23.4

Sorted Data Set: 26, 29, 33, 47, 56, 58, 65, 74, 78, 83, 97

Range = Maximum - Minimum

Range = 97 - 26 = 71

Based on the values, we can say that

Option A) Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.

Please help me!!!!!! I really neeeeeeed
Butoxors [25]

Answer:

A-(x+4,y-5)

B- move 1 unit left and 7 units down

Step-by-step explanation:

A- 4 units right is x so

(x+4,y__)

5 units down is y so

(x+4,y-5)

B- move 1 unit left and 7 units down

because (x-1,y__) is going left because of the subtraction sign and its the x-coordinate, and (x-1,y-7) is down because its a Y-coordinate and sub so its going down.

<h2><u>TIP- Going left/down is always subtract/negative going right/up is positive/addition.</u></h2>

6) What is the mean (average) of this set of data: 3 4 6 7 10 15 19 21
Natali5045456 [20]

Answer:

10.62

Step-by-step explanation:

Mean can be described as the average of a sum of numbers, it can be calculated by sum ing all the numbers together and then diving by the total

The mean of the set of numbers shown in the question above can be calculated as follows

3+4+6+7+10+15+19+21/8

= 85/8

= 10.62

Hence the mean is 10.62
