Look at the variable "payroll" in the data set "payroll". it has 50 values, all between 100 and 400. count the number of values in each of the intervals 100 160, 160 220, 220 - 280, 280 - 340, 340 - 400. can you conclude that this data does not come from the uniform distribution on the interval (100,400)? (hint: if the distrbution is uniform, what is the expected count in each interval) the counting can be done with r's histogram fiunction > paycounts-hist (payrollspayroll, breaks-seq(100,400,60))scounts > paycounts do the calculations by hand, except for finding the p-value. then check your work by using r's "chisq. test" function > chisq. test (paycounts)
