Question

17) Suppose you will perform a test to determine whether there is sufficient evidence to support a

Answer 1

Answer: C.  ±0.632.

Step-by-step explanation:

We have given,

Sample size : n= 10

Significance level : $\alpha=0.05$

Test to check determine whether there is sufficient evidence to support a

claim of a linear correlation between two variables is a two tailed test.

Degree of freedom(df) = n- 2=8

Now , by the correlation coefficient(r) table ,

The critical r value corresponding to df = 8 and Significance level = 0.025  (0.05/2) is ±0.632.

Hence, the correct option is C.  ±0.632.
