**. **A random sample of *n *= 16 individuals is selected from a population with μ = 70, and a treatment is administered to each individual in the sample. After treatment, the sample mean is found to be *M *= 76 with *SS *= 960.

**a. **How much difference is there between the mean for the treated sample and the mean for the original population? (*Note: *In a hypothesis test, this value forms the numerator of the *t *statistic.)

**b. **How much difference is expected just by chance between the sample mean and its population mean? That is, find the standard error for *M*. (*Note: *In a hypothesis test, this value is the denominator of the *t *statistic.)
