MP-3 players, and most notably the Apple iPod, have become an industry standard for people who want to have access to their favorite music and videos in a portable format. The iPod can store massive numbers of songs and videos with its 120-GB hard drive. Although owners of the iPod have the potential to store lots of data, a recent study showed that the actual disk storage being used is normally distributed with a mean equal to 1.95 GB and a standard deviation of 0.48 GB. Suppose a competitor to Apple is thinking of entering the market with a low-cost iPod clone that has only 1.0 GB of storage. The marketing slogan will be “Why Pay for Storage Capacity that You Don’t Need?”
Based on the data from the study of iPod owners, what percentage of owners, based on their current usage, would have enough capacity with the new 1-GB player?
