Given the following dataset
Dataset for question (11)
x | 1 | 1 | 2 | 3 | 4 | 5 |
---|---|---|---|---|---|---|
y | 0 | 2 | 4 | 5 | 5 | 3 |
We want to test the claim that there is a linear correlation between x and y.
(a) What is the null hypothesis H0 and the alternative hypothesis H1?
(b) Using α=0.05, will you reject H0? Justify your answer by using a p-value.
(c) Base on your answer in part (b), is there evidence to support the claim?
(d) Find r, the linear correlation coefficient.
