nhtemp is a built-in R time series that records the mean average temperature in New Haven from
1912 to 1971.the values in nhtemp can be converted to a vector using the assignment x <-
as.vector(nhtemp) :
x <- as.vector(nhtemp)
We can see the values in x by typing x and Return or Enter. Remember x <- as.vector(nhtemp)
After this assignment, we can see the first six values in x by typing head(x) and Return or Enter
a. If x is defined as above then what is the 15th element of vector x?
b. Calculate the interquartile range of x using the R, IQR() function.
c. Calculate the sum of the squares of the values in x.
d. Calculate the sample mean of x.
e. Calculate the sample variance of x.
f. Calculate the sample standard deviation of x.
g. Using R, calculate a
trimmed mean of x.
h.Enter your R script in the box below.
