Question
The ages of a random sample of people who attended a recent soccer match are as follows:$\begin{array}{lllllll}23 & 35 & 14 & 37 & 38 & 15 & 45 \\ 12 & 40 & 27 & 13 & 18 & 19 & 23 \\ 37 & 20 & 29 & 49 & 40 & 65 & 53 \\ 18 & 17 & 23 & 27 & 29 & 31 & 42 \\ 35 & 38 & 22 & 20 & 15 & 17 & 21\end{array}$a. Find the mean age.b. Find the standard deviation.c. Find the coefficient of variation.
Step 1
The ages are: 23, 35, 14, 37, 38, 15, 45, 12, 40, 27, 13, 18, 19, 23, 37, 20, 29, 49, 40, 65, 53, 18, 17, 23, 27, 29, 31, 42, 35, 38, 22, 20, 15, 17, 21. Show more…

Calculate the mean deviation about median age for the age distribution of 100 persons given below: $$ \begin{array}{|c|c|c|c|c|c|c|c|c|} \hline \begin{array}{c} \text { Age } \\ \text { (in years) } \end{array} & 16-20 & 21-25 & 26-30 & 31-35 & 36-40 & 41-45 & 46-50 & 51-55 \\ \hline \text { Number } & 5 & 6 & 12 & 14 & 26 & 12 & 16 & 9 \\ \hline \end{array} $$
Statistics
Introduction
Find the $(a)$ mean, $(b)$ variance and $(c)$ standard deviation of the binomial distribution for the given random variable, and (d) interpret the results. Life on Mars Thirty-one percent of adults think that life existed on Mars at some point in time. You randomly select six adults and ask them whether they think life existed on Mars at some point in time. The random variable represents the number of adults who think that life existed on Mars at some point in time.
