You have obtained the number of years of education from one random sample of 38 police officers from City A and the number of years of education from a second random sample of 30 police officers from City B. The average years of education for the sample from City A is 15 years with a standard deviation of 2.5 years. The average years of education for the sample from City B is 14 years with a standard deviation of 2.2 years. Is there a statistically significant difference between the education levels of police officers in City A and City B? What is the appropriate test for this case? A. 2 sample paired t-test B. Chi-square test C. 2 sample z-test D. 2-sample t-test Carry out the test. The test statistic =( ) (round answer to two decimal places.) and the p-value is ( ) (round answer to 2 decimal places) There (is/is not) sufficient evidence at the 5% level to conclude that the education levels of police officers in City A and City B is significantly different.
