Four buses carrying 151 high school students arrive to Montreal. The busescarry, respectively, 35, 41, 31, and 44 students. One of the students is randomlyselected.Let X denote the number of students that were on the bus carrying this randomlyselected student. One of the four bus drivers is also randomly selected.Let Y denote the number of students on his bus. Compute the expectations andvariances of X and Y:E(X) =Var(X) = =E(Y) = 37.75Var(Y)=

There are total 151 students & Bus carry respectively 35,41,31,44 students.

We have a large dataset which we denote by D1, with values x1, x2, x3, ..., xN. Its mean is denoted by m. We create a new dataset D2 as follows: x1-m, x2-m, x3-m, ..., xN-m (that is, we subtract the mean from every data point). Then we create a new dataset by dividing every value in D2 by number 5. (so note that we said D2, not D1). What is the mean of D3? Group of answer choices 5 m m/5 m/ 25
