The shelf life of a battery produced by one major company is known to have a mean life of 5 years and a standard deviation of 0.1 years. what value of shelf life do 16% of the battery shelf lives fall below? round your answer to one decimal place.

Thus 16% of batteries fall below a life of 4.9 years.(Answer rounded to 1 decimal place)

Step-by-step explanation:

Taking normal distribution of shelf life we have

Given that mean life = 5 years

standard deviation = 0.1 years

Thus standard deviate factor 'Z' corresponding to an area of 16% = -0.994

thus we have

Applying values we get

Thus 16% of batteries fall below a life of 4.9 years.
