A light-rail service claims to be on time 98% of the time. Jeanette takes the light-rail 43 times one month, how many times can she predict she will be on time? Is the light-rail's claim accurate if she is late 6 times? Complete the explanation to answer the question. Round to the nearest whole number.
She can predict she will be on time *blank.*
times out of 43. The light-rail's on-time claim is higher than the actual
*blank*% if she is late 6 times.

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
