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

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:

where are data points, is the mean and n is the number of observations.  

Sum of squares of differences = 5460.18

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.

one that is bigger than 3 1/2

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
