longley is a built-in R data.frame which is sometimes used in economics to study regression. We are interested in some descriptivestatistics related to the Employed column of the longley data.frame. We can access this data directly by using the assignmentx <- 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, 70.551You should get these values from the R assignment above rather than manually entering the data.e. Calculate the sample mean of x.f. Calculate the sample variance of x.g. Calculate the sample standard deviation of x.h. What proportion of the x values are less than 1 sample standard deviation from the sample mean?i. Calculate the sample median of x.j. What is the 9th element of x?k. How many of the elements of x are smaller than the sample mean of x?

Solution -Given that , The values of x are as follows x: 60.323, 61.122, 60.171, 61.187, 63.221,…

Select the most appropriate response. If the correlation between a person’s age and annual income is 0.60, then the coefficient of determination tells us that: 36% of the variation in a person’s annual income can be explained by the predictor variable age. 36% of a person’s annual income can be explained by their age 60% of the variation in a person’s annual income can be explained by the predictor variable age 60% of a person’s annual income can be explained by their age
