The following data represent glucose blood levels (mg/100 ml) after a 12-hour fast for a random sample of 70 women (Reference: American Journal of Clinical Nutrition, Vol. 19, pp. 345-351).

45	66	83	71	76	64	59	59	76	82
80	81	85	77	82	90	87	72	79	69
83	71	87	69	81	76	96	83	67	94
101	94	89	94	73	99	93	85	83	80
78	80	85	83	84	74	81	70	65	89
70	80	84	77	65	46	80	70	75	45
101	71	109	73	73	80	72	81	63	74

For this problem, use six classes.(a) Find the class width.

(b) Make a frequency table showing class limits, class boundaries, midpoints, frequencies, relative frequencies, and cumulative frequencies. (Round your relative frequencies to four decimal places.)

Class Limits	Class Boundaries	Midpoint	Frequency	Relative Frequency	Cumulative Frequency
−  −  −  −  −  −	−  −  −  −  −  −

(c) Draw a histogram.
