For the following exercises where applicable:

a. State the hypotheses and identify the claim.
b. Find the critical value(s).
c. Compute the test value.
d. Make the decision.
e. Summarize the results.
Use the traditional method of hypothesis testing unless otherwise specified. Assume all variables are normally distributed.

It has been hypothesized that the standard deviation of the germination time of radish seeds is 8 days. The standard deviation of a random sample of 60 radish plants’ germination times was 6 days. At α = 0.01, test the claim.
