Exercise 1.17

1.17 Make a stemplot. Here are the scores on the first exam in an introductory statistics course for 30 students in one section of the course:

82	73	92	82	75	98	94	57	80	90	92	80	87	91	65
73	70	85	83	61	70	90	75	75	59	68	85	78	80	94

Use these data to make a stemplot. Then use the stemplot to describe the distribution of the first-exam scores for this course.

82	73	92	82	75	98	94	57	80	90	92	80	87	91	65
73	70	85	83	61	70	90	75	75	59	68	85	78	80	94

82	73	92	82	75	98	94	57	80	90	92	80	87	91	65
73	70	85	83	61	70	90	75	75	59	68	85	78	80	94

82	73	92	82	75	98	94	57	80	90	92	80	87	91	65
73	70	85	83	61	70	90	75	75	59	68	85	78	80	94
