What is the product of the elements in column vector v (defined in the R script)? Question 4 What is the value of the element in matrix m in row 4 and column 6 ? Question 5 What is the sverage of the second column of matrix m ? What is the maximum value in the third row of matrix m? Question 7 What is the number of columns in matrix m plus the number of rows in matrix m ? Question 8 A) Create variable called rows equal to row 5 of matrix m. B) What is the the result of mulriplying row 5 by v? What is the scalar value resulting from multiplying the transpose of column " X _ 1 " in data frame f by column " X2 " in f ? The data frame f is defined in the provided R script. Question 10 1pts Randomly generate 10000 values for variable y using the model: y=1+2x+e Where: x is a normally distributed random variable with mean 0 and variance 1 e is a nomally distributed random variable with mean Q and variance 1 : x and e are independent random variables What is the absolute vatue of the difference between your sample variance of y and the population variance of y. aven the model for y and the distributions of x and e
