Question

What percent of undergraduate enrollment in coed colleges and universities in the United States is male? A random sample of 50 such institutions give the following data.

Percent Males Enrolled in Coed Universities and Colleges
47	33	45	40	36	37	46	41
40	42	31	73	50	47	40	49
44	41	49	30	53	44	53	34
49	52	60	51	36	38	27	35
44	35	46	35	33	52	43	31
22	60	34	54	28	33	43	53
44	40

For this problem, use five 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 two decimal places.)

Class Limits	Class Boundaries	Midpoint	Frequency	Relative Frequency	Cumulative Frequency

(f) Draw an ogive. (Graph each point and the closed line segments connecting the points to create your graph.)

Answer 1

Answer:

Given data,

47,33,45,40,36,37,46,41,40,42,31,73,50,47,40,49,44,41,49,30,53,44,53,34,49,52,60,51,36,38,27,35,44,35,46,35,33,52,43,31,22,60,34,54,28,33,43,53,44,40

Maximum Value = 73

Minimum Value = 22

No. of classes n = 5

Class Width = (max. value - min. value) / n = (73-22) / 5 = 10.2 = 11
