Question 7:

(Part 1)

Use the code and output below to answer the following questions.

a) Which difference variable of the newly created variables is most positively correlated (if any) to which of the original TCI variables of (NSTCI, HATCI, RDTCI, PTCI)? Give the associated correlation and p-value.

b) Which difference variable of the newly created variables is most negatively correlated (if any) to which of the original TCI variables of (NSTCI, HATCI, RDTCI, PTCI)? Give the associated correlation and p-value.

c) Which pair of difference variables is most positively correlated to which other difference variable, and give the associated correlation and p-value? Is the correlation statistically significant and why? Explain why you think a positive correlation is to be expected in this case, or not.

d) Which pair of difference variables is most negatively correlated (if any) to which other difference variable and give the associated correlation and p-value? Is the correlation statistically significant and why? Explain why you think a negative correlation is to be expected in this case, or not.

e) What is p for the mathematical formulation used in the SAS code for the analysis in this question

Dataset:

The dataset called “Dataset_new” is created below. This dataset has three newly created variables, “x1_x2”, “x1_x4” and “x2_x3”.
