Question

For a data set of brain volumes cm3 and IQ scores of seven males, the linear correlation coeficent is r=0.743. Use the table available below of t. Based on a comparison of the linear correlation coefficient r and the critical values, what do you conclude about a linear correlation? find the critical values Click the icon to view the table of critical values of r The critical values are Type integers or decimals. Do not round. Use a comma to separate answers as needed.) Since the correlation coefficient r is I-there | | sufficient evidence to support the claim of a linear correlation. 2 Enter your answer in the answer box.

Explanation / Answer

N = 7

df = N-2 = 7-2 = 5

So, from the critical tables, we have the fact that for N=5, .755, which is more than .743.

The critical values are -.755,.755

Since the correlation coefficient r is less than the critical value (i.e. .743<.755), there is sufficient evidence to support the claim of a linear correlation
