a. Explanation Calculation: From Histogram (i), it can be observed that the class with the highest frequency (=13) is 4-5. Midpoint: The midpoint of the class 4-5 is given below: Midpoint= ( 4 + 5 ) 2 = 9 2 = 4.5 ≈ 5 From Histogram (ii), it can be observed that the class with the highest frequency (=20) is 3-4 b. To determine Find the range of data in each histogram using class midpoints. c. To determine Identify the histograms that are skewed right. d. To determine Check whether the three random samples follow the given properties of population.
