A restaurant is open for both lunch and dinner. One day, the owner kept track of the number of occupied tables in the dining area and created a histogram showing the results for each half-hour of the day. What shape does the distribution have? A histogram. A histogram has a horizontal axis labeled Time of Day from 9 to 21 in increments of 3 and a vertical axis labeled Frequency from 0 to 20 in increments of 5. The histogram contains vertical bars of width 0.5 starting at the horizontal axis value 9. The heights of the bars are as follows, where the left horizontal axis label is listed first and the frequency is listed second: 9, 1; 9.5, 1; 10, 2; 10, 5; 11, 9; 11.5, 10; 12, 11; 12.5, 10; 13, 7; 13.5, 3; 14, 3; 14.5, 4; 15, 4; 15.5, 6; 16, 4; 16.5, 6; 17, 7; 17.5, 10; 18, 12; 18.5, 15; 19, 12; 19.5, 10; 20, 7; 20.5, 6. All vertical coordinates are approximate. Select the correct answer below: uniform unimodal and symmetric unimodal and left-skewed unimodal and right-skewed bimodal
