Answer: approximately normal
Step-by-step explanation:
The first step to determine the percentage of increase is to
compute for the difference of consumer price index in value.
231.11 (consumer price index for 2012) – 211.4 (consumer
price index for 2007) = 19.71 (increase)
To compute for the percentage of increase, you need to
compare the increase to the consumer price index for 2007.
19.71/211.4 = 9.3% increase
3 and 2 should be the only roots
Try making a proportion 10,000/1 and then 1000/x and solve
1)b
2)a
