Final answer:
Explanation of why a 1-year warranty for cell phones is appropriate based on an exponential distribution.
Explanation:
Exponential distribution models the lifetime of cell phones. With a 3-year average lifetime, the manufacturer replaces phones failing within 2 years. Based on the exponential distribution, it's statistically appropriate to offer 1 year of warranty covering 5% of failures annually due to the nature of the distribution.
