Compare the appropriate measures of center and variability for the two sets of data.    Data Set A has a higher mean value of 8.8, and Data Set B has a lower range value of 8.  Data Set A has a higher median value of 9, and Data Set B has a lower IQR value of 2.5.  Data Set A has a lower mean value of 8.8, and Data Set B has a higher range value of 8.  Data Set A has a lower median value of 9, and Data Set B has a higher IQR value of 8.

The length of time it takes for a worker to perform certain task (in minutes) was recorded for 10 workers. The resulting data values were the following: 5, 3, 11, 7, 6, 9, 4, 8, 7, 10 Find the mean, median, mode, range, variance and standard deviation. In the answers for the mean, variance, and standard deviation leave one digit after decimal point. a. Mean = d. Range = b. Median = e. Variance = c. Mode = f. Standard deviation =

The following refer to the following data set: 52.2 20.1 38.2 16.4 52.2 44.7 35.6 26.9 52.2 31.2 What is the arithmetic mean of this data set? mean = What is the median of this data set? median = What is the mode of this data set? mode =

You may need to use the appropriate appendix table or technology to answer this question. According to the Vivino website, suppose 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 65 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. (Enter != for ≠ as needed.) H0:     Ha:     (b) Using the sample from the 65 bottles, what is the test statistic? (Round your answer to three decimal places.)…
