Question
![Mickey Mantle played for the New York Yankees for 18 years from 1951 to 1968. Year by year he hit the following numbers of home runs: 13, 23,
21, 27, 37, 52, 34, 42, 31, 40, 54, 30, 15, 35, 19, 23, 22, 18. We represent these as a vector x in R by making the following assignmemt:
x <-c(13, 23, 21, 27, 37, 52, 34, 42, 31, 40, 54, 30, 15, 35, 19, 23, 22, 18)
Define the vector y by the assignment
y <- cumsum(x)
Define the variable w using the assignment
w <-714-y
Define z with the assignment
z <-c(X,Y,W)
x, y, w and z are vectors. Answer the following using R code.
f) What is the 18th element of w? (value of w[18]) 1
h) Calculate the sample variance of 5*x 713.268
i) What is the length(# of elements) in 5*x|
j) How many unique(different) values are in z? 49
