One-Way Airfares The average one-way airfare from Pittsburgh to Washington D.C. is $236. A random sample of 20 one-way fares during a particular month had a mean of $222 with a standard deviation of $43. At a=0.05, is there sufficient evidence to conclude a difference from the stated mean? (a) State the hypothesis and identify the claim with the correct hypothesis. (b)Find the critical value(s). Round the answer to decimal places, if necessary. If there is more than one critical value, separate them with commas. (c)Compute the test value. Round score to at least three decimal places. (d)Make the decision. (e)Summarize the results. (f)Use the sample statistics to construct a 98% confidence interval for the true mean one-way airfare from Pittsburgh to Washington, D.C. Round your answers to two decimal places. (g)Do they support or contradict one another?
A leasing firm claims that the mean number of miles driven annually, µ, in its leased cans is less than 12460 miles. A random sample of 27 cars leased from this firm had a mean of 11839 annual miles driven. It is known that the population standard deviation of the number of miles driven in cars from this firm is 1620 miles. Assume that the population is normally distributed. Is there support for the firm’s claim at the 0.05 level of significance? The null hypothesis: H0 : _____ The alternative hypothesis: H1: ______ The type of test statistic: (choose one) _______ The value of the test statistic: ______ (round to at least three decimal places.) The p-value: _____ (round to at least three decimal places.) Can we support the leasing firm’s claim that the mean number of miles driven annually is less than 12460 miles? Yes _____, NO ______
A random sample of 23 bags of apples (marked as 10 pounds each) received by a large grocery chain tested out as having a mean of 9.2 pounds with a variance of 2.56 pounds. Test whether the true mean of all bags is under 10 pounds. Set up hypotheses. Perform the appropriate test by showing your formula. Interpret the results using a Type I (alpha) error of .05. Also provide the p value here. Also construct a 95% confidence interval around your sample mean (X bar) that should contain the true mean (mu). Also interpret this interval.
The test statistic in a two-tailed test is z=0.67. Determine the P-value and decide whether, at the 10% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. Click here to view a partial table of areas under the standard normal curve. The P-value is. (Round to four decimal places as needed.)

Even though the population standard deviation is unknown, an investigator uses z rather than the more appropriate t to test a hypothesis at the .05 level of significance. Is the true level of significance larger or smaller than .05? Is the true critical value larger or smaller than that for the critical z?
