(Round to two decimal places as needed.)What does the interval imply?O A. Since the mean age from the earlier year is not contained in the interval, there is sufficient evidence to conclude that the mean age had changed.O B. Since the mean age from the earlier year is contained in the interval, there is not sufficient evidence to conclude that the mean age had changed.tsOC. Since the mean age from the earlier year is not contained in the interval, there is not sufficient evidence to conclude that the mean age had changed.OD. Since the mean age from the earlier year is contained in the interval, there is sufficient evidence to conclude that the mean age had changed.

In a confidence interval, the margin of error measures the amount of sampling error. Margin of error…
