The width of bolts of fabric is normally distributed with mean 950 mm (millimeters) and standard deviation 10 mm.
a What is the probability that a randomly chosen bolt has a width of between 947 and 958mm?
b What is the appropriate value for C such that a randomly chosen bolt has a width less than C with probability .8531?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
