1. Individuals are assigned a happiness score (H) and a contentment score (C). Both take values in the interval (0-100), with 100 representing total happiness or contentment respectively. For a sample of 245 individuals, it is found that the correlation between H and C is 0.32.
If we define an unhappiness score, U=100-H and a discontentment score D=100-C, then the correlation between U and D for these 245 individuals is equal to what?
2. It has been reported that high levels of dioxin are associated with heavy exposure to Agent Orange, a herbicide sprayed in South Vietnam between 1962 and 1970.
The dioxin concentrations (in parts per trillion) for a sample of army combat personnel who served in Vietnam during 1967 and 1968 were recorded. The disribution of these readings was strongly skewed to the right (positively skewed). So it is best to describe the distribution by reporting correlation or five number summary?
