According to the Vivino website, the mean price for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is $32.48. A New England-based lifestyle magazine wants to determine if red wines of the same quality are less expensive in Providence, and it has collected prices for 56 randomly selected red wines of similar quality from wine stores throughout Providence. The mean and standard deviation for this sample are $30.15 and $12, respectively. a. Develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48. Ho: - Select your answer - Ha: -Select your answer - b. Using the sample from the 56 bottles, what is the p-value? The p-value is - Select your answer - c. At a = 0.05, what is your conclusion? - Select your answer the null hypothesis. We - Select your answer conclude that the price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48. d.

According to the Vivino website, the mean price for a bottle of red wine that scores 4.0 or higher on the Vivino Rating
System is $32.48. A New England-based lifestyle magazine wants to determine if red wines of the same quality are less
expensive in Providence, and it has collected prices for 56 randomly selected red wines of similar quality from wine stores
throughout Providence. The mean and standard deviation for this sample are $30.15 and $12, respectively.
a. Develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean
price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population
mean of $32.48.
