Question
Is the crime rate in New York different from the crime rate in New Jersey? Independent random samples from region A (cities in New York) and region B (cities in New Jersey) gave the following information about violent crime rate (number of violent crimes per 100,000 population). (Reference: U.S. Department of Justice, Federal Bureau of Investigation.)
Region A | 467 | 454 | 409 | 607 | 562 | 503 | 602 | 516 | 610 | 590 | 453 | |
Region B | 406 | 569 | 517 | 408 | 532 | 465 | 501 | 457 | 443 | 617 | 613 | 524 |
Use a 10% level of significance to test the claim that there is no difference in the crime rate distributions of the two states.
