Step 1: I'll solve this step by step using the class boundaries concept.. Step 2: : Understand Class Boundaries. Class boundaries are the real limits of a class interval. They are calculated by finding the midpoints between the upper and lower limits of adjacent classes. Step 3: : Calculate Lower Class Boundary. For the interval 50-59, the lower class boundary is the value that separates this class from the class below it. - Lower adjacent class is not shown, so we use the midpoint between the lower limit of the given class and the lower limit of the next class. - Lower limit of 50-59 class is 50 - Lower limit of next class (60-69) is 60 Step 4: : Calculate Upper Class Boundary. - Upper limit of 50-59 class is 59 - Upper limit of next class (60-69) is 69 Step 5: : Compute Boundaries. Upper boundary: $\frac{59 + 69}{2} = 59.5$ Step 6: : Verify the Answer Choices. Final Answer: a) $49.5-59.5
