Question
For Questions 1A to 1E start with an R command that creates Data, a vector of numerical data with the integers from 1 to 5
DataA <- 1:5
- What is the value of
sum(DataA * DataA)
- What is the value of
Length(Append(DataA, DataA))
- What is the value of
if (DataA [3] > (Data[1] + 1) & DataA[5] < 10) 27 else 13
- What is the value of
if (5 %in% (DataA*2)) 27 else 13
- What is the value of:
sum(floor(DataA / 6))
Expert Solution
Step 1
1A.
Consider the following statement:
sum(DataA * DataA)
- The value of DataA * DataA is [1, 4, 9, 16, 25]. The sum of the elements is 1 + 4 + 9 + 16 + 25 = 55.
The output will be 55.
