The population (in millions) and the violent crime rate (per 1000) were recorded for 10 metropolitan areas. The data are shown in the following table. Do these data provide evidence to reject the null hypothesis that ƒÏ = 0 in favor of ƒÏ ‚ 0 at ƒ¿ = .05? (Give your answers correct to three decimal places.)

Population 9.2 4.3 3.4 8 5.3 5.1 0.3 3.3 5.5 3.8
Crime Rate 12.9 7.6 9 7.4 9.2 6.6 7.7 8.1 6.5 8.4

(a) Calculate r.
0.444

(ii) Calculate the critical region.
(smaller value)
(larger value)
