A repeating process produces parts having a mean size of 55 inches, a standard deviation of 1 inch, and a "normal" shaped distribution of values. Approximately (BLANK)% of the parts produced on this process will be expected to fall between the values of 54 and 56, with about (BLANK)% of the parts expected to have values less than 54, and about (BLANK)% of the parts expected to have values more than 56.

The production of pipes has a mean diameter of 3.25 inches and a standard deviation of .15 inches. The shape of the distribution is approximated by a normal distribution since approximately an equal number of parts are above or below average, and most parts are very close to the mean value. A part will be discarded is it has a diameter of greater than 3.5 inches or less than 3 inches. What proportion of parts are discarded from the production...

Male heights have a mean of 70 inches and a standard deviation of 3 inches. Thus, a man who is 73 inches tall has a standardized score of 1. Female heights have a mean of 65 inches and a standard deviation of 2 ½ inches. These measurements follow, at least approximately, a bell-shaped curve. What do you think this means? Explain in your own words. What is the standardized score corresponding to your own height? Does this value show that...
