Question
The following sample was obtained from a population with unknown parameters. Scores: 6, 12, 0, 3, 4 a) Compute the sample mean and standard deviation. (note that these are descriptive values that summarize the sample data.) b) Compute the estimate standard error for M. ( note that this is an inferential value that describes how accurately the sample mean represents the unknown population mean.)The following sample was obtained from a population with unknown parameters.

Explanation / Answer
That would be... Mean: (6 + 12 + 0 + 3 + 4)/5 = 5 Standard Deviation: v([(6 - 5)² + (12 - 5)² + (0 - 5)² + (3 - 5)² + (4 - 5)²]/(5 - 1)) ˜ 4.472
