Suppose the president claims that at least 80 percent of the company's 5,000 customers are satisfied. Again, 100 customers are surveyed using simple random sampling. The result: 73 percent are very satisfied. Based on these results, should we accept or reject the president's hypothesis? Assume a significance level of 0.05.
