Question

Below are the numbers of 11 players randomly selected from a football team Find the range, variance, and standard deviation for the giver sample data. What do the results toll us? 23 45 42 89 27 98 53 56 78 43 88 Range (Pound to one decimal place as needed.) Samplo standard deviation - Round to one decimal places needed) Sample variance (Round to one decimal place as needed.) What do the results tellus? OA. The sample standard deviation is to large in comparison to the rugo. OB Jersey numbers on a football team very much more than expected OC Jersey numbers on a football team do not was much as expected OD. Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.

Answer 1

Solution: Given Calculation table for mean, 6 Х 26 (x-772 944.3329 137.5929 (hi Range 2 Max- min 45 298-26 Range : z 72 42 216.9729 624 89 1041.3529 Meanet Exiz h 27 e 56.73 883.8729 1 1703.2/29 98 variane ħ {X-5/2 5712.1919 Z 11 53 55 78 Variance z 519.289 2.5193 13.9129 2.9929 452.4129 188.5129 127.9129 {2 571201819 Standard deviation 2 Ivariance 43 68 E2 624 z J579.289 Standard deviating 2 22.79 2 22.8 Standard deviation is 22.8. 9t is sufficient dispersion with respect to mean (56.73). so, obtion ® is correct answer.
