Problem Set 1

Solution

1) advertising, building upgrades, and education = 7:8:10

Total =150000

Total in proportion =25

Thus 1 in proportion = 6000

Thus we get advt = 42000

Blg upgrades = 48000

Education = 60000

2)  6 cases of kitten food, a living catnip plant, and a scratching post tower. The basic kit costs $30 and the exotic kit costs $150. Kitten lovers bought 10 times as many basic kits than exotic kits last month.

Kitten food x 6 6x

Catnip

3) Arithmetic Mean = 2.5247

First quartile = 2.09+2.14/2 = 2.125

Third quartile = 3.01+3.02/2 = 3.015

c) Range = 3.22-1.38 = 1.84

Interquartile range = 3.015-2.125 = 0.890

Std deviation = 0.4949

Variance = 0.2449

Coeff of variation = std dev / mean =0.1977

Central tendency:

Median = 2.52 and Mode = 1.98,2.52,3.01,3.04,3.06
