Disk drives hаve been getting lаrger. Their cаpacity is nоw оften in terabytes (TB) where 1 TB = 1000 gigabytes, оr about trillion bytes. A survey of prices for external disk drivers has been conducted. After correcting for an outlier, the data look like this: ( bar{x} =0.0628 bar{y}=79.8 ) SD(x)= 0.751 SD(y)=61.8 r=0.989 We want to predict Price from Capacity. 1. [10 points] Find the slope and the intercept of the least-square regression line by showing how to plug in the formulas at page 7 of Chapter 4 power point slides using the summary statistics in the table. 2. [5 points] What would you predict for the price of a 2.0 TB drive? 3. [5 points] You found a 2.0 TB drive for $200. Is this a good deal? How does the price compare to what you expected to pay? How much would you save or overspend? 4. [10 points] What is the value of r2? How to interpret it? Is this a suitable model to analyze such data?
