A 95% confidence interval for the mean starting wage of welders in Georgia is found to be $19.60 to $23.12 per hour. A person claims that the mean starting wage of electricians in a specific region is $23. According to the confidence interval which of the following is the best response? We believe that $23 is almost for sure the correct population mean wage. We agree that 99% of all welders in Georgia probably have a starting wage of $23 per hour. We believe that $23 is not a plausible value for the mean wage. We can't dispute the claim that the mean wage is $23 but we do not believe the wage is exactly $23 either because there are a lot of other values in the interval too.
