Considering the home market value data provided as a population
of homeowners on this street, compute the mean, variance, and
standard deviation for each of the variables using a spreadsheet
and these formulas. Verify your calculations using the appropriate
Excel function.
Identify the number of data values for the house age data. The number of data values is 15. (Type a whole number.) Compute the mean of the house age data. The population mean of the house age data is 29.87. (Round to two decimal places as needed.) Compute the deviation from the mean for the first house's age of 33 years. The deviation from the mean is 3.13. (Round to two decimal places as needed.) Compute the variance of the house age data. The population riance the house age data is 5.98. (Round to two decimal places as needed.) Compute the standard deviation of the house age data. The population standard deviation of the house age data is 2.45. (Round to two decimal places as needed.) Compute the mean of the square feet data. The population mean of the square feet data is 1723.6. (Round to two decimal places as needed.) Compute the deviation from the mean for the first house's square footage of 1,850 square feet. ▼ The deviation from the mean is 126.40.
The deviation from the mean is 126.40. (Round to two decimal places as needed.) Compute the variance of the square feet data. The population variance of the square feet data is 37322.64. (Round to two decimal places as needed.) Compute the standard deviation of the square feet data. The population standard deviation of the square feet data is 193.19 (Round to two decimal places as needed.) Compute the mean of the market value data. The population mean of the market value data is $ 93,066.67. (Round to two decimal places as needed.) Compute the deviation from the mean for the first house's market value of $96,000. The deviation from the mean is $2933.33. (Round to two decimal places as needed.) Compute the variance of the market value data. The population variance of the market value data is $ 99,667,555.56. (Round to two decimal places as needed.) Compute the standard deviation of the market value data. The population standard deviation of the market value data is $ 9,983.36. (Round to two decimal places as needed.)
