Three years and one month is equivalent to the mean minus one standard deviation.
Three years and seven months is equivalent to the mean plus one standard deviation.
For a normal distribution, we know that 68% of population is between mean ± 1 sd, then can be expected that 25000*68% = 17000 of batteries last between three years and one month and three years and seven months
Answer:
Step-by-step explanation:
Principle x Rate x Time
(550,000) (0.02) (360) = 3,960,000
Interest = 3,960,000
