The lifetimes of a certain type of automobile tire have been found to be distributed normally with a mean lifetime of 130,000 km and a standard deviation of 1,700 km.
A) Find the Z-Score of a tire that has a lifetime of 126,005 km: Z-
(Round to two decimal places)
B) Find the lifetime of a tire if it has a z score of - 1.96: Lifetime - km
(Round to nearest whole number)
