Could you show me how to solve the attached problem #1.
It's long, but it's still a basic statistics problem.
It asks four questions:
a) What is the sample distribution of "d"?
b) What assumptions made in a) are checked by the plots?
c) Calculate a 95% confidence interval for the difference, if 12 other points are collected.
d) Draw a boxplot
Thanks for any assistance you can give.
This solution is provided in 520 words in an attached .doc file. It uses rules of a normal distribution to find standard deviation, uses calculations to solve for confidence interval, and includes a boxplot to satisfy the question.
