The table shows the numbers of emails sent and the numbers of emails received in a week for a random sample of nine people. At \(\alpha=0.01\), can you conclude that there is a significant correlation between the number of emails sent and the number of emails received?

(a) identify the claim and state \(H_{0}\) and \(H_{a}\),

(b) decide which nonparametric test to use,

(c) find the critical value(s),

(d) find the test statistic,

(e) decide whether to reject or fail to reject the null hypothesis,

(f) interpret the decision in the context of the original claim.
