rwo =
(Round to three decimal places)
Homework Answers
Answer #1
a) With outlier:
Statistics software output:
Hence, r = 0.879 (rounded to 3 decimal places)
b) The last data point is the outlier. When we remove it then statistics software output:
Hence, r = -0.181 (rounded to 3 decimals)
I hope this will help. Thank you.
