Essay

The weights of five players on a football team are shown below. $$\begin{array} { r | c c c c c } \text { Player } & \text { A } & \text { B } & \text { C } & \text { D } & \text { E } \\ \hline \text { Weight (lb) } & 290 & 310 & 250 & 255 & 220 \end{array}$$ Consider these players to be a population of interest. The mean weight, µ, for the population is 265 pounds. Construct a table that shows all of the possible samples of size two. For each of the possible samples, list the players in the sample, their weights, and the sample mean. The first line of the table is shown below. $$\begin{array} { c | c | c } \text { Sample } & \text { Weights } & \overline { \mathrm { x } } \\ \hline \mathrm { A } , \mathrm { B } & 290,310 & 300 \end{array}$$ Use your table to find the probability that, for a random sample of size two, the sample mean will equal the population mean.
