It is known that Michelin tyres last on average for 43 thousand km witl a standard deviation of 5 thousand km. If the chances are 93.28% tha the lifetime of a tyre will be within symmetrical limits, say K1 and K2, then K1 and K2 are respectively equal to: a. K1 = 36.35 thousand km, K2 = 49.65 thousand km b. K1 = 33.85 thousand km , K2 = 52.15 thousand km %3D Oc K1 = 31 4 thousand km K2 = 54 65 thousand km
