1.e.

1f. The range is the difference between the highest and lowest values in the data set.

Ordering the data from least to greatest, we get:

43 46 46 51 58 63 65 70 74

The lowest value is 43.

The highest value is 74.

The range = 74 - 43 = 31.

1g. To find variance first we need to find mean

Create the following table.

data	data-mean	(data - mean)²
46	-11.3333	128.44368889
51	-6.3333	40.11068889
63	5.6667	32.11148889
65	7.6667	58.77828889
74	16.6667	277.77888889
46	-11.3333	128.44368889
58	0.6667	0.44448889
70	12.6667	160.44528889
43	-14.3333	205.44348889
