longley is a built-in R data.frame which is sometimes used in economics to study regression. We are interested in some descriptive statistics related to the Employed column of the longley data.frame. We can access this data directly by using the assignment x<-longley$Employed (In R, use? Longley for info on this data) The values of x if assigned as above are: [1] 60.323, 61.122, 60.171, 61.187, 63.221, 63.639, 64.989, 63.761 [9] 66.019, 67.857, 68.169, 66.513, 68.655, 69.564, 69.331, 70.551 You should get these values from the R assignment above rather than manually entering the data. b. Calculate the 3rd quartile of x using the R summary function c. Calculate the sample range & median of x h. What proportion of the x values are less than 1 sample standard deviation from the sample mean? k. How many of the elements of x are smaller than the sample mean of x?
