#4 A manufacturer of automobile batteries states that their "slow die" battery has a mean life of \( 50 \) months with a standard deviation of \( 8 \) months. If a consumer protection group randomly selects one of these batteries, what is the probability that it will last: 

(a) less than \( 52 \) months? 

(b) between \( 52 \) and \( 60.88 \) months? 

Answer

P( X ≤ 52 ) = 0.598706. P( 52≤ X ≤ 60.88 ) = 0.314379.
