Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your finding to state whether or not the given r represents a significant linear correlation. Use a significant level of 0.05. r=0.105, n=15

Unfortunately, I didn't get any options. Do you know if there is a way to figure this out in excel? Any ideas you have or suggestions will be highly appreciated.

You can use this table : http://cnx.org/content/m17098/latest/ Degrees of freedom = 15 - 2 = 13 The critical region is $\pm 0.514$ Since your given r is 0.105 is found within this region, you should conclude that there is no significant linear correlation.
