The following scattergram is derived from the data given: Income Expenses 24 3.6 15 2.9 18.2 2.9 12.6 2.6 8 2 9.5 2.4 21 3 11.4
2.5 6.4 1.8 13.2 2.4 The
regression equation is: y = .0872 x 1.3955 The food expenditure of a family with an
income of $20,000 is 3.139, calculated from the regression equation and visible on the scattergram above. The student can calculate the coefficient of
correlation (sx=5.394) and the coefficient of determination using the stepwise instructions found at a UNESCO site (11.6. Correlation analysis, n.d.). 2. Distribution Frequency
Polling a group of 50 employees to discover how many hours of training they had received over the previous quarter returned this raw data: 11, 2, 0, 13,
5, 7, 1, 8, 12, 11, 7, 8, 9, 10, 7, 4, 6, 10, 4, 7, 8, 6, 7, 10, 7, 3, 11, 18, 2, 9, 7, 3, 8, 7,
3, 13, 9, 8, 7, 7, 10, 4, 15, 3, 5, 6, 9, 7, 10, 6. The resulting frequency table follows. The
shape of the distribution is a triangle with its top angle about 70 degrees. Beginning and ending numbers are the same, but those in the middle prevent the triangle
from being equilateral. Hours of Number of % of Training Employees Total 0
