The Bureau of Labor Statistics generally uses 90% confidence levels in its reports. One report gives a 90% confidence interval for the mean hourly earnings of American workers in2000 as $15.49 to $16.11. If the null hypothesis states that the mean hourly earnings of all workers in 2000 was $16.15, would this hypothesis be rejected in a two-tailed test if a = .10? What about a null hypothesis stating that the mean was $15.50? Explain your reasoning.(You should not need to do a significance test to answer this question.)
