For the following sample, answer the following: Remember you can copy and "paste special" the table into the Excel sheet. Here is a sample of the cost of new cars. 34000 31000 37000 28000 27000 38000 39000 29000 40000 25000 26000 30000 Here is a sample of grades on a test. 63 66 84 30 85 89 83 34 79 96 87 71 What is the mean of the grades? What is the sample standard deviation of grades? As expected the cost of cars have a higher standard deviation, since the cost of cars is more spread out than the grades. What is the sample coefficient of variation of grades? Therefore, while the cost of cars have a higher standard deviation, the costs of cars have a lower coefficient of variation and are less spread out relative to their average cost.

What is the
What is the sample standard deviation of grades?
As expected the cost of cars have a higher standard deviation, since the cost of cars is more spread out than the grades.
What is the sample coefficient of variation of grades?
Therefore, while the cost of cars have a higher standard deviation, the costs of cars have a lower coefficient of variation and are less spread out relative to their average cost.
