What do the results tell us?11253722846176143445972a. Find the mean. The mean is .45.2(Type an integer or a decimal rounded to one decimal place as needed.)b. Find the median.The median is .37(Type an integer or a decimal rounded to one decimal place as needed.)c. Find the mode.Select the correct choice below and, if necessary, fill in the answer box to complete your choice.A.The mode(s) is(are) .(Type an integer or a decimal. Do not round. Use a comma to separate answers as needed.)B.There is no mode.d. Find the midrange.The midrange is .49.5(Type an integer or a decimal rounded to one decimal place as needed.)e. What do the results tell us?A.Since only of the jersey numbers were in the sample, the statistics cannot give any meaningful results.11B.The mean and median give two different interpretations of the average (or typical) jerseynumber, while the midrange shows the spread of possible jersey numbers.C.The midrange gives the average (or typical) jersey number, while the mean and median give two different interpretations of the spread of possible jersey numbers.D.The jersey numbers are nominal data and they do not measure or count anything, so the resulting statistics are meaningless.
