A labor organization claims that the median weekly earnings of male workers is greater than \(\$ 950\). To test this claim, you randomly select 70 male workers and ask each to provide his weekly earnings. The table shows the results. At \(\alpha=0.01\), can you support the organization's claim?

Use a right-tailed test and

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

(b) find the critical value,

(c) find the test statistic,

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

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