1. EXERCISE R.13 R.13Let  HT be the correlation between humidity, H, and temperature measured in degrees Fahrenheit, F. Demonstrate that the correlation coefficient is unaffected if temperature is instead measured in degrees Celsius, C. Note: C = 5/9(F – 32). 1

2. EXERCISE R.13 R.13Let  HT be the correlation between humidity, H, and temperature measured in degrees Fahrenheit, F. Demonstrate that the correlation coefficient is unaffected if temperature is instead measured in degrees Celsius, C. Note: C = 5/9(F – 32). We start by noting that 2

3. EXERCISE R.13 3 We start with the definition of the correlation between H and C and substitute for C i – C.

4. EXERCISE R.13 4 The 5/9 terms cancel and we are left with the definition of the correlation between H and F.
