The sample means for three samples of 20 are shown in the table.

A 3-column table with 3 rows. Column 1 is labeled Sample with entries Sample 1, Sample 2, Sample 3. Column 2 is labeled Sample Mean with entries 12, 8, 16. Column 3 is labeled Actual mean with entries 10.5, 10.5, 10.5.

Compute the variation of each predicted population mean from the sample means in the table.

Sample 1: answer (1.5)
Sample 2: answer (-2.5)
Sample 3: (5.5)

Write the expression as a single natural logarithm. 2 in a - 4 in y
