1. [4.6/5 Points] DETAILS PREVIOUS ANSWERS MYNOTES PRACTICE ANOTHER Consider a population of tive families with the foliowing daca representing the number of pets in each famaly. \begin{tabular}{|c|c|} \hline Family & Number of Pets \\ \hlineL & 2 \\ \hlineM & 7 \\ \hlineN & 6 \\ \hlineO & 4 \\ \hlineP & 1 \\ \hline \end{tabular} (a) Determine the mean (in pets) and the variance of the population, mean (b) There are ten possible samples of size 2 (sampling without repiacement). List the 10 possible samples of size 2, and determine the mean of each sample. (Enter your samples as alphabetically ordered comma-separated lists. Order your samples alphabetically by first value, then alphabetically by second value.) (c) Using the ten sample mean values, compute the mean and the standard deviation (in pets) from the mean determined. (Round your standard deviation to three decimal placess.) mean. pecs standard deviation 2.167 x pets
