5) b) 25th percentile = 8,400,000 75th percentile = 22,650,000 11) Sample variance = =(4+1+9)/2 7 The 25th percentile means that 25% of the companies have sales less than $ 8.4 mil ion. The 75th percentile means that 75% of the companies have sales less than $ 22.65 mil ion. Sample Standard Deviation = =√7 2.65 12) c) Minimum $6,600,000.00 6) CV = =((2.65)/7)*100 maximum $450,000,000.00 37.85714 Average $33,536,000.00 7) I would prefer a the test score of 75 cause I would be in the third deviation from the mean which Median $13,000,000.00 means that I would have done bet er than the rest compared to what I would do with a score of 80 when the average is 68, when the scores are standardised.

The Mean is larger than the median as the data is skewed positive. 1) Average = (40+40+40+80)/ 4 = 50 8) d) Weighted Average = (40*40) + (40*40)+ (40*40)+(80*80) / (40+40+40+80) = 56 2) False.
