In a factory the time it takes to assemble given equipment varies from worker to worker, but it is known that the distribution of assembly time is normal with the mean of 100 minutes and with the standard deviation of 10 minutes.

The old management gave a bonus to the workers whose assembly time was at most 85 minutes. What proportion of workers got the bonus?

Do I do (85-100)/10=-1.5 so the p-value is 0.0668

Is that the answer?
