(a) What is the range that a correlation coefficient (r) can take? (b) When we calculate the 95% confidence interval using a correlation coefficient, the interval might have the value beyond the range. To prevent this issue, what statistic technique can be performed?
Homework Answers
a) range that a correlation coefficient (r) can take is from -1 to 1 (both inclusive)
b) Yes, sometimes 95% confidence interval using a correlation coefficient, the interval might have the value beyond and that happens when the data set is not normal and shows non-normality. To overcome this type of inaccurate problem, we used techniques like converting the data to approximate normal data using non -linear transformation techniques like Logarithms

To be specic, suppose the R-vector p=c(.1,.2,.3,.35, .02, .03) gives the desired probabilities. Write R code that produces a number from 1 to 6 with the given probabilities, without using if statements. I recommend using the R command cumsum to do this, though there many possible approaches. 2.
