Question

i pe: Using the test describe in "How to test for correlation" (see question above), test the null hypothesis Efn=12, t=3.1, a = 0.01 Choose the right conclusion. a) There is not enough evidence at the a=0.01 level to conclude that there is a linear relationship in the population between the predictor x and response y. b) there is sufficient evidence at the a=0.01 level to conclude that there is a linear relationship in the population between the predictor x and response y c) there is not enough data to draw any conclusion ob Ос 1 pts Question 9

Answer 1

Here

The value of t statistic t = 3.1

and critical value $t_{critical} = \pm t_{\frac{0.01}{2},n-2}=\pm t_{0.005,10} = \pm 3.169$

Since | t statistic |  $\ngtr$ critical value, we fail to reject H₀ at 0.01 level of significance and we can conclude that there is no significant linear relationship between predictor x and response y.

ans-> a)
