Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.5. (Round your answers to four decimal places.) (a) If the distribution is normal, what is the probability that the sample mean hardness for a random sample of 16 pins is at least 51? (b) What is the (approximate) probability that the sample mean hardness for a random sample of 45 pins is at least 51?

The drying time of a type of paint under specified test conditions is known to be...

The drying time of a type of paint under specified test conditions is known to be normally distributed with mean value 75 min and standard deviation 9 min. Chemists have proposed a new additive designed to decrease average drying time. It is believed that drying times with this additive will remain normally distributed with σ = 9 min. Because of the expense associated with the additive, evidence should strongly suggest an improvement in average drying time before such a conclusion...
