41	76	10	53	36	86	42	81	104	77
44	25	68	90	94	90	125	25	32	13

98	74	28	82	107	110	44	10	72	27

Exchange 60 sample observations above to grouped data by means of frequency distribution. Consider first class be 10 < 30 and keep class width at 20. Disregard 2^k Rule for determining number of classes. From frequency distribution, compute sample mean and variance, and standard deviation using grouped data formulas. Make the histogram, frequency polygon, and Ogive. Find out less than cumulative frequency distribution before you can give Ogive. Then use ogive to estimate median and first and third quartiles. Also utilize it to reply following question: What percent of 60 mutual fund loads are less than 75.
