An economist studying inflation in electricity prices in 2018 and 2019 believes that the average price of electricity, even after adjusting for inflatichanged between these two years. To test his claim, he samples 9 different counties and records the average price of electricity in each countyfrom each year. He then adjusts the prices for inflation. His results are given in the following table. Test the economist's claim at the 0.05 level osignificance assuming that the population distribution of the paired differences is approximately normal.

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.
