Suppose the Rockwell hardness of a particular alloy is normally distributed with mean 71 and standard deviation 3.
The Rockwell hardness of a metal is determined by impressing a hardened point into the surface of the metal and then measuring the depth of penetration of the point. Suppose the Rockwell hardness of a particular alloy is normally distributed with mean 71 and standard deviation 3. (a) If a specimen is acceptable only if its hardness is between 70 and 74, what is the probability that a randomly chosen specimen has an acceptable hardness? (Round your answer to four decimal...

There are 60 calories on average in a Tootsie Roll Pop with a standard deviation of 2 calories. Assume that the calories are normally distributed. What is the probability that a randomly selected Tootsie Roll Pop has less than 55 calories? (round to four decimals) What is the probability that the mean number of calories of a sample of 12 Tootsie Roll Pops have less than 55 calories? (round to four decimals)
Suppose the Rockwell hardness of a particular alloy is normally distributed with mean 69 and standard deviation 3.
The Rockwell hardness of a metal is determined by impressing a hardened point into the surface of the metal and then measuring the depth of penetration of the point. Suppose the Rockwell hardness of a particular alloy is normally distributed with mean 69 and standard deviation 3. (a) If a specimen is acceptable only if its hardness is between 68 and 73, what is the probability that a randomly chosen specimen has an acceptable hardness? (Round your answer to four decimal...
