To see whether silicon chip sales are independent of where the XYZ country’s economy is in the business cycle, data have been collected on the weekly sales of ABC firm, and on whether the economy was rising to a cycle peak, at a cycle peak, falling to a cycle trough, or at a cycle trough. The results are given in the table below. State the null and alternative hypotheses. Calculate the appropriate test statistic and conduct the test of hypothesis at 0.01 level of significance, what is your conclusion?
