ne range of the sample data is Round to one decimal place as needed.) The standard deviation of the sample data is Round to one decimal place as needed.) The variance of the sample data is (Round to one decimal place as needed.) What important feature of the data is not revealed through the different measures of variation? O A. The measures of variation reveal no information about the scale of the data. O B. The measures of variation reveal nothing about how the numbers of hurricanes are spread. O C. The measures of variation reveal nothing about the pattern over time. O D. The measures of variation do not reveal the difference between the largest number of hurrica

Questions A and B. Please!

3. Complete the first 3 columns of the table below. Values Deviations Square deviations X - X X (X-X)² Standard (z) scores X - X S Z= a. Compute the sample variance and sample standard deviation by definition. b. Fill in the last column of the table c. Compute the coefficient of variation.

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.The artifact frequency for an excavation of a kiva in Bandelier National Monument gave the following information.
