**Cost of Personal Computers** The average price of a personal computer (PC) is $949. If the computer prices are approximately normally distributed and the standard deviation (σ) is $100, consider the following: 1. What is the probability that a randomly selected PC costs more than $1200? 2. The least expensive 10% of personal computers cost less than what amount? 3. Calculate the probability that a PC costs between $500 and $800. **Mean**: 949 **Standard Deviation**: 100
