$$\mathrm { r } = 0.353 , \mathrm { n } = 15$$
A) Critical values: $\mathrm { r } = \pm 0.514$, no significant linear correlation
B) Critical values: $r = \pm 0.532$, no significant linear correlation
C) Critical values: $\mathrm { r } = 0.514$, no significant linear correlation
D) Critical values: $\mathrm { r } = \pm 0.514$, significant linear correlation

Quizplus · Accepted Answer

The critical value for a two-tailed test with 15 observations is 0.514. Since the absolute value of the correlation coefficient (0.353) is less than the critical value, there is no significant linear correlation.

r=0.353,n=15\mathrm { r } = 0.353 , \mathrm { n } = 15r=0.353,n=15

$\mathrm { r } = 0.353 , \mathrm { n } = 15$
