Question

A light-rail service claims to be on time 98% of the time. If Jeanette takes the light-rail 40 times one mouth, how many times can she predict she will be on time? Is the light-rail's claim accurate if She is late 6 times?

Answer 1

If Jeanette take its 40 times in one month she would be on time 39 (39.2) times.

NO, the light-rails claim is not accurate if she is late 6 times.

The light rails claim would be accurate if it stated the service is on time 85% of the time.
