Answer #1

The null and alternate hypothesis are:

H0:

Ha:

From the data,

So, the sample correlation coefficient:

The test statistic is given by:

Since this is a two-tailed test, so the p-value is given by:

Since p-value is greater than 0.05, so we have sufficient evidence to reject the null hypothesis
H0 at 5% level of significance.

Thus we can say that i.e. there is no significant correlation between the two sets.
