24. A community researcher measured the correlation between the average cost of housing and the crime rate in eight local communities. The results of this hypothetical study are listed in the following table.

Average Cost of Housing (in thousands of dollars)	Crime Rate (per 100,000 population)
X	Y
20	96
80	65
220	22
120	31
180	34
90	70
110	30
300	16

1. Compute the Pearson correlation coefficient.
2. Compute the coefficient of determination.
3. Using a two-tailed test at a .05 level of significance, state the decision to retain or reject the null hypothesis.
