Construct a frequency histogram for the following data. 6, 2, 1, 6, 4, 3, 4, 5, 5, 3, 6, 3 a. A histogram with 6 class labels along the horizontal axis is given. The horizontal axis is labeled: x. The vertical axis is labeled: f(x). Vertical rectangles are drawn centered over the respective class labels. Moving left to right, information about the rectangles (beginning with class label) is listed below. 1: 1 unit tall 2: 1 unit tall 3: 3 units tall 4: 2 units tall 5: 2 units tall 6: 4 units tall b. A histogram with 6 class labels along the horizontal axis is given. The horizontal axis is labeled: x. The vertical axis is labeled: f(x). Vertical rectangles are drawn centered over the respective class labels. Moving left to right, information about the rectangles (beginning with class label) is listed below. 1: 2 units tall 2: 2 units tall 3: 3 units tall 4: 2 units tall 5: 2 units tall 6: 3 units tall c. A histogram with 6 class labels along the horizontal axis is given. The horizontal axis is labeled: x. The vertical axis is labeled: f(x). Vertical rectangles are drawn centered over the respective class labels. Moving left to right, information about the rectangles (beginning with class label) is listed below. 1: 1 unit tall 2: 1 unit tall 3: 3 units tall 4: 2 units tall 5: 2 units tall 6: 3 units tall d.
