 A statistician wishes to determine whether current unemployment rates differ between Urban and Rural areas of the United States. A sample of ten states each was randomly chosen from all 50 states. The data are as follows:   Urban: 23%, 13%, 33%, 21%, 17%, 24%, 12%, 18%, 27%, 16%  Rural: 12%, 8%, 9%, 14%, 7%, 8%, 10%, 11%, 12%, 7%  Are the mean percentages significantly different? And

what are the degrees of freedom?

a. yes, at p < .05

b. yes, at p < .01

c. yes, at p < .001

d. no, at p > .05


Solutions

Expert Solution

degree of freedom is calculated using the formula

Here to conduct the test i have chose the significance level 0.05, but you can see that the p value is less than 0.001, Since the null hypothesis is rejected so option c is right
