Statistical Abstracts (117th edition) reports that the average amount spent annually forfood by householders under 25 years of age is $2,690. A random sample of 16 peopleunder 25 years of age who live in a university neighborhood were surveyed. The surveyshowed that they spent a sample mean amount of $3,220 with sample standard deviation$750. Test the claim that the mean for this neighborhood is different from the nationalaverage. Use a 5% significance level. Assume our data is normally distributed.a) State the null and alternate hypotheses.b) Would you perform a one-tailed or two-tailed test?

Twenty years ago, 52% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 281 of 800 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the a=0.1 level of significance. *** Because npo (1-Po) = 199.7 less than 5% of the population size, and the sample can be reasonably assumed to be random, the 10, the sample size is requirements for testing the hypothesis are satisfied.

The Census Bureau's American Housing Survey has reported that 76 percent of families choose their house location based on the school district. You want to conduct a test of whether the population proportion really equals 0.76. Use a 0.10 level of significance and a sample of 440. The proportion of families in your sample that choose their home based on the school district was 0.78. a. State in statistical terms the null and alternative hypotheses. (2 points) b. Determine the appropriate test statistic. (z or t) (2 points) c. Determine the critical values. (2 points) d. Compute the test statistic. (2 points) e. Make a decision on the hypotheses.

While her husband spent 2½ hours picking out new speakers, a statistician decided to determine whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy shopping for electronic equipment. The population was Saturday afternoon shoppers. Out of 68 men, 24 said they enjoyed the activity. Eight of the 23 women surveyed claimed to enjoy the activity. Interpret the results of the survey. Conduct a hypothesis test at the 5% level. Let the subscript m= men and w= women. What is the test statistic? (If using the distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.) What is the p-value? (Round your answer to four decimal places.) Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the p-value. i. ii. iii.
