a 2-column table with 2 rows. column 1 is a labeled sample with entries 1, 2, 3, 4. column 2 is labeled sample mean with entries 8, 5, 6, 4.
which statements are true? check all that apply.
the variation in the sample means is less than 5.
the variation in the sample means makes population predictions invalid.
the actual population mean most likely will be between 4 and 8.
the sample means can be used to make predictions about the population mean.
