the true length of boards cut at a mill with a listed length of 10 feet is normally distributed. the mill knows that their customers will tolerate no more than 10% of the boards falling below the listed length of 10 feet. when more than 10% of the boards fall below 10 feet, the mill shuts down their saw for maintenance. calculate the probability of a board being less than the listed length of 10 feet given the current mean of 120.54 inches and standard deviation of 0.5 inches. (report your answers precisely to 4 decimal places as determined using the cumulative z-table. owl is using the cumulative z-table to determine probabilities. 2 Part B) Based on your calculated probability, should they shut down the saw for maintenance? (Enter "yes" or "no.") ____________
