Question
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.
Correct: 0.444 .
(ii) Calculate the critical region.
(smaller value)??
(larger value)??

F test
Kuai
are you test F statistic?
Tracy
I tried the F test calculator and that does not give me the answers that are needed. I have looked for one for critical region and have been unable to find one at this time.
Kuai
F statistic = 1.866
F cirtical = 5.32
Tracy
Sorry this is not right
Kuai
Are you two tail
Tracy
I think so
Kuai
F statistic =1.854
Cirtical F value = 4.026
