According to the Bureau of Labor Statistics, the average hourly wage in the United States was $26.84 in April 2018. To confirm this wage, a random sample of 35 hourly workers was selected during the month. The average wage for this sample was $25.13. Assume the standard deviation of wages for the country is $4.75. Complete parts a and b. a. Are the results of this sample consistent with the claim made by the Bureau of Labor Statistics using a 95% confidence interval? The confidence interval is $ sxss The Bureau's claim between the lower limit and the upper limit of the confidence interval, so the results of the sample V consistent with the claim. (Round to two decimal places as needed.]
