# $1.$ Look at the murders data set by using library$($dslabs$)$ data$($murders$).$# $2.$ Callculated the murder rate using total $/$ population $*100,000$# $3.$ Check if the murder$\_$rate is less than $0\mathrm{.}71$# $4.$ Define a function to check the average value of the total. CANNOT use mean$().$# $5.$ Write an if$-$else statement to check if the first value of abb is AK$.$ If so return "YES", if not, reture "NOT AK$".$# $6.$ Write a for$-$loop statement to display all abb value. Tips: check the length of abb at first and then use the length to define the i in for loop.
