2. Construct a frequency table by using the intervals below. Then sketch the histogram. Times Frequency 124 - 125 126 - 127 128 - 129 130 - 131 132 - 133 134 - 135 3. Calculate the following (where x = lap times [in seconds]): a. x = _______ b. s = _______ 4. Construct a histogram for the frequency table above. 5. Draw a smooth curve through the tops of the bars of the histogram. Write one to two complete sentences to describe the general shape of the curve. (Keep it simple. Does the graph go straight across, does it have a v-shape, does it have a hump in the middle or at either end, and so on?)
