Consider a random sample of size 32 from a population with hypothesized mean 3.14 and s = 6.8.

a. Write the four parts for a one-sided, left-tailed hypothesis test concerning the population mean with a = 0.001.

b. What assumptions are made in order for the test in part (a) to be appropriate?

c. Compute the sample mean, and find the value of the test statistic. Draw a conclusion about the population mean.

 Consider a random sample of size 48 from a population with hypothesized mean 365.25 and s =22.3.

a. Write the four parts for a two-sided hypothesis test concerning the population mean with a = 0.05.

b. What assumptions are necessary in order for the test in part (a) to be appropriate?

c. Suppose the sample mean is x = 360.0. Find the value of the test statistic, and draw a conclusion about the population mean.
