Consider the means of the samples shown in the table. Which value is least likely to be the mean of the population from which the samples were taken?SampleSample Mean115.2217.1316.9412.2518.0616.3717.4

The sample means are 15.2, 17.1, 16.9, 12.2, 18.0, 16.3, and 17.4. Their average is about 16.2, which is a reasonable estimate of the population mean. Of the choices, 12.2 is farthest from 16.2, so it is least likely to be the population mean.
