A real estate agent believes that the values of houses in the neighborhood she works in have increased from last year. To test this claim, she selects random houses in this neighborhood and compares their estimated market values in the current year to their estimated market values in the previous year. Suppose that data were collected for a random sample of 8 houses, where each difference is calculated by subtracting the market value of the previous year from the market value of the current year. Assume that the values are normally distributed. What type of test is this hypothesis test? Select the correct answer below: O This is a right-tailed test because the alternative hypothesis is H, 0 This is a two-tailed test because the alternative hypothesis is Ha: Ha 0 O This is a right-tailed test because the alternative hypothesis is H: Mu 0. 0 . 0 This is a left-tailed test because the alternative hypothesis is Ha: Hd 0 This is a left-tailed test because the alternative hypothesis is Ha: Hd0 .
