Question: Never one to rest on his laurels, Bob Warren is at it again with the good folks at PCC, but this time they are researching what makes companies in Prescott County successful versus the unsuccessful ones. An economics professor, Dr. Jack Gloomy (remember economics is called the dismal science) has a hypothesis that if you measure the current ratio of a company (the amount of what the firm is worth divided by what the firm owes) that you can predict successful companies. To prove his point he and Bob surveyed 72 firms that are classified as successes and found that they had an average current ration of 1.69 with a standard deviation of 0.67. They found the former owners of 33 unsuccessful firms who were currently all working at the Prescott Casket Company (go figure) and found that their current ratio was 0.85 with a standard deviation of 0.44. At the .05 level of significance, write the null and research hypotheses for this study and figure out if Dr. Gloomy and Bob are correct or not. Remember to show your work.
