Cloudy County is also concerned about its property crimes. The County Commissioner asks you to do some analysis of the distribution of property crimes based on data from many prior years. Historically, the number of property crimes are normally distributed with a mean of 500 and a standard deviation of 60. You will be asked to show your work as a file upload on the next question, so keep it handy. a. Based on the information above, what proportion of years (i.e. what proportion of the data) had a number of property crimes greater than 525? Round your final answer to the third decimal place. [answera] b. Based on the information above, what proportion of years (i.e. what proportion of the data) had a number of property crimes between 450 and 550? Round your final answer to the third decimal place. [answerb] c. Last year, Cloudy County experienced a crime wave. Only 2.56 percent (so, proportion = 0.0256) of previous years had a higher prevalence of crime. How many crimes did Cloudy County have last year? [answerc]
