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

 

  1. What is the value of

sum(DataA * DataA)

 

 

  1. What is the value of

       Length(Append(DataA, DataA))

 

  1. What is the value of

       if (DataA [3] > (Data[1] + 1) & DataA[5] < 10) 27 else 13

 

  1. What is the value of

       if (5 %in% (DataA*2)) 27 else 13

 

  1. 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.
