Question 2 1 pts Suppose regs.out is a list of 100 Im objects -- i.e. each element of regs.out was returned by a call to Im. What does the code sapply(regs.out,function(x){return(sum(x$residuals^2)}}) return? O Avector of length 100, each entry of which is the sum of squared residuals from the regression whose results are stored in the corresponding entry of regs.out. O Alist with 100 elements, each of which is the vector of residuals from the regression whose results are stored in the corresponding entry of regs.out. O Alist with 100 elements, each of which is the sum of squared residuals from the regression whose results are stored in the corresponding entry of regs.out. O Avector consisting of the residuals from each of the regression models whose output is stored in regs.out, stacked in the order in which the models appear in regs.out
