Explanation Given info: The test statistic is, z = 2 , the claim of the test is p > 0.5 and the significance level is α = 0.05 . Calculation: From the claim, it can be observed that the test is right tail. That is, the symbol “>”represents the test is right-tailed. P-value: Software procedure: Step-by-step procedure to obtain P -value using the MINITAB software is as follows: Choose Graph > Probability Distribution Plot choose View Probability > OK. From Distribution , choose ‘ Normal ’ distribution. Click the Shaded Area tab. Choose X Value and right tail for the region of the curve to shade. Enter the data value as 2

PCB contamination of a river by a manufacturer is being measured by amounts of the pollutant found in fish. A company scientist claims that the fish contain only 5 parts per million, but an investigator believes the true figure is higher. What is the conclusion if six fish are caught and show the following amounts of PCB ( in parts per million ) 6.8, 5.6, 5.2, 4.7, 6.3, and 5.4? Test at 5% significance level. In addition to your conclusions, you must provide the null and alternative hypothesis , alpha and the p-value.

Test the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats at the 0.01 significance level. Based on a sample of 80 men, 25% owned catsBased on a sample of 20 women, 45% owned catsThe test statistic is: (to 2 decimals)The positive critical value is: (to 2 decimals)

Technology. In Exercises 9–12, test the given claim by using the display provided from technology. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value (or range of P-values), or critical value(s), and state the final conclusion that addresses the original claim. Old Faithful Data Set 23 “Old Faithful” in Appendix B includes data from 250 random eruptions of the Old Faithful geyser. The National Park Service makes predictions of times to the next eruption, and the data set includes the errors (minutes) in those predictions. The accompanying Statdisk display results from using the prediction errors (minutes) to test the claim that the mean prediction error is equal to zero. Comment on the accuracy of the predictions. For Exercise 11
