Assume that the paired data came from a population that is normally distributed. Construct a 95% confidence interval for the mean of all differences x - y.
x1 15 3 7 10 15 18 2 16
y1 14 6 10 14 15 13 7 14
Find 95% confidence interval and round to 1 decimal place.
Can you help me through the entire process? I keep messing up somewhere. My homework wants only the final answer, so even when I have the wrong final answer, I am not able to tell where I went wrong with my formulas and calculations.
I need this for a homework problem due tonight by 10pm.
Thank you,
K.
