(a)State the hypotheses and identify the claim with the correct hypothesis.
:H0: claim/not claim?
:H1: claim/not claim?
This hypothesis test is a one-tailed test/two-tailed test?
(b)Find the critical value(s).
Round the answers to three decimal places, if necessary. If there is more than one critical value, separate them with commas.
Critical value(s):
(c)Compute the test value. Round the intermediate calculations to three decimal places and the final answer to three decimal places.
(d) Make a decision: Reject/Do not reject the null hypothesis
(e)Summarize the results.
There ▼(Choose one) enough evidence/not enough evidence, to support the claim that the standard deviation
