Question 1
The most committed crimes somewhere around 2009 and 2011 were: Burglary, Filter, Forcible Sex Offense, and Motor Vehicle Theft.
Crime rates decreased essentially somewhere around 2009 and 2011 focused around a rundown of the information (incorporated in the table beneath) gave by the state. On the other hand, Filter and Forcible Sex Offense increased over the 2 years (U.S. Department of Education., 2012).

The huge distinction between Means of the 2 examples is sufficient confirmation that the crime rates in public institutions are more prominent. Subsequently, the invalid hypothesis ought not to be rejected (U.S. Department of Education., 2012).
Question 3
The distinction of the crime rates is 1003-912 = 81
81 will be utilized as the example size.
The standard deviation of the 2 gatherings is 21. The standard deviation speaks to the standard lapse of the testing appropriation.
Expecting that the alpha is 0.05, there is a need to focus, by computation, the region secured by the general (standard) ordinary bend. The standard bend ought to equivalent 95%, or 1-alpha. This worth speaks to + or -1.96. Subsequently, in the development of the confidence level, the accompanying equation applies:
On the other hand, the confidence interval can be created by utilizing the strategies beneath:
81 - (1.96) (21) and 81 + (1.96) (21)
81 – (1.96) (21) = 39.84 and 81 + (1.96) (21) = 122.16
