Write the four parts for a one-sided right-tailed


Consider a random sample of size 21 from a normal population with hypothesized variance 16.7.

a. Write the four parts for a one-sided, right-tailed hypothesis test concerning the population variance with a = 0.01.

b. Suppose σ2 = 28. Find the value of the test statistic, and draw a conclusion about the population variance.

c. Find bounds on the p value associated with this hypothesis test, and carefully sketch a graph to illustrate this value.
