4 . A machine makes spherical balls. Diameters X are normally distributed with mean 240.0 mm and standard deviation 3.0 mm. Another machine, working independently, makes sockets with diameters Y that are normally distributed with mean 249.0 mm and standard deviation 4.0 mm. A ball will fit into the socket only if ; otherwise the ball is too big for the socket. Define the “gap” to be the difference between the socket diameter and the ball diameter. Therefore a ball...

A process manufactures ball bearings with diameters that are normally distributed with mean 25.15 mm and standard deviation 0.08 mm. a) A particular ball bearing has a diameter of 25.2 mm. What percentile is its diameter on? (Round up the final answer to the nearest whole number.) b) To meet a certain specification, a ball bearing must have a diameter between 25.0 and 25.3 millimeters. What proportion of the ball bearings meet the specification?

Engineers must consider the diameters of heads when designing helmets.
Engineers must consider the diameters of heads when designing helmets. The company researchers have determined that the population of potential clientele have head diameters that are normally distributed with a mean of 5.7-in and a standard deviation of 1-in. Due to financial constraints, the helmets will be designed to fit all men except those with head diameters that are in the smallest 3.1% or largest 3.1%.What is the minimum head diameter that will fit the clientele?min = What is the maximum...
