A geographer studying West Africa would like to know the size of stones in the delta region where the Niger River runs into the Gulf of Guinea. He collects 53 stones and measures the diameter of each, and so obtains the following measurements, in centimeters as seen below in the frequency table. Size (cm) Frequency [0, 2) 17 [2, 4) 13 [4, 6) 10 [6, 8) 7 [8, 10) 4 [10, 12) 2 a. Create a histogram for the measured stones. Include all labels. b. How many stones are larger than or equal to 6 cm? c. What fraction of stones are below 6 cm? d. If you randomly picked up a stone in the Niger River, what is more likely: a stone that measures below 6 cm or above 6 cm? Give your reasoning by writing a simple sentence.
