True
Thank you so much for your help
False.
The class interval of 25-29 has real limits of 24.5 and 29.5. The lower real limit is always obtained by subtracting 0.5 from the lower class boundary, and the upper real limit is obtained by adding 0.5 to the upper class boundary. Therefore, the real limits for the class interval of 25-29 would be 24.5 and 29.5.
True.
To determine the real limits of a class interval, you take the midpoint of each class interval and subtract or add 0.5.
In this case, the midpoint of 25-29 is (29 + 25) / 2 = 27. The lower real limit is 27 - 0.5 = 26.5, and the upper real limit is 27 + 0.5 = 27.5.
Therefore, the class interval of 25-29 has real limits of 26.5 and 27.5.
