Carry out a hypothesis test to determine if the mean rating assigned to the wine when the cost is described as $90 is greater than the mean rating assigned to the wine when the cost is described as $10. Use a = 0.01. (Use = Hs9n - Hs10:) Find the test statistic. (Round your answer to one decimal place.) Find the df. df = Find the P-value. (Use technology to calculate the P-value. Round your answer to three decimal places.) P-value = State your conclusion. O Fail to reject Ho. We have convincing evidence that mean rating for the tasting is greater when the cost is described as $90 than when the cost is described as $10. O Reject Hg. We have convincing evidence that mean rating for the tasting is greater when the cost is described as $90 than when the cost is described as $10. O Reject H. We have no evidence that mean rating for the tasting is greater when the cost is described as $90 than when the cost is described as $10. O Fail to reject H. We have no evidence that mean rating for the tasting is greater when the cost is described as $90 than when the cost is described $10.

Question
A study investigated whether price affects people's judgment. Twenty people each tasted six cabernet sauvignon wines and rated how they liked them on a scale of 1 to 6. Prior to tasting each wine, participants were told the price of the wine. Of the six wines tasted, two were actually the same wine, but for one tasting the participant was told that the wine cost $10 per bottle and for the other tasting the participant was told that the wine cost $90 per bottle. The participants were randomly assigned either to taste the $90 wine first and the $10 wine second, or the $10 wine first and the $90 wine second. Differences were calculated by subtracting the rating for the tasting in which the participant thought the wine cost $10 from the rating for the tasting in which the participant thought the wine cost $90. Difference ($90 - $10) 1 0 21 4 3 1 3 3 4 1 2 2 -2 In USE SALT Carry out a hypothesis test to determine if the mean rating assigned to the wine when the cost is described as $90 is greater than the mean rating assigned to the wine when the cost is described as $10. Use a = 0.01. (Use u = He90 - HE10:) Find the test statistic. (Round your answer to one decimal place.) t = Find the df. df = Find the P-value. (Use technology to calculate the P-value.
