Question 909173: the diameters of bolts produced by a certain machine are normally distuributed with a mean of 0.25 inches and a stanard deviation of 0.01 inches what percentage of bolts will have a diameter greater than 0.24 inches Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! *Note:
P( t > .24) = 1 - P( t ≤ .24) = 1 - P(z ≤ (-.01/.01) = 1 - P(z ≤ -1) = 1 - .1587 = .8413 0r 84.13%
84.13% the Area under the Curve to the right of blue line.
