Disk drives have been getting larger

Their capacity is now often given in terabytes (TB) where 1 TB = 1000 giga- bytes, or about a trillion bytes. A survey of prices for external disk drives found the following data:

.080	29.95
.120	35.00
.200	299.00
.250	49.95
.320	69.95
1.0	99.00
2.0	205.00
4.0	449.00

b) What can you say about the direction of the association?

c) What can you say about the form of the relationship?
