Suppose a group of students (N=30) participated in CSUN Pumpkin Pie Eating Contest. Each of the following number represents the number of pie slices each student ate. Answer the following questions (Show calculations process) (Report your answers up to two decimal points).

student 1:27, student 2:18, student 3:20, student 4:32, student 5:15, student 6:25, student 7:24, student 8:12, student 9:2, student 10:18, student 11:14, student 12:20, student 13:11, student 14:23, student 15:14, student 16:10, 17:14, 18:33, 19:34, 20:28, 21:14, 22:17, 23:19, 24:22, 25:13 26:14 27:22 28:27 29:28 30:30

1. Determine the mean, medium, and mode

2. Determine the estimate of the standard deviation

3. Graph the data, evaluate the skewness of the distribution. is it positively skewed or negatively skewed
