Problem 38E

There are two machines available for cutting corks intended for use in wine bottles. The first produces corks with diameters that are normally distributed with mean 3 cm and standard deviation .1 cm. The second machine produces corks with diameters that have a normal distribution with mean 3.04 cm and standard deviation .02 cm. Acceptable corks have diameters between 2.9 cm and 3.1 cm. Which machine is more likely to produce an acceptable cork?

Step-by-Step Solution:

Answer : Step 1 : Given,there are two machines available for cutting corks intended for use in wine bottles. The first produces corks with diameters that are normally distributed with mean 3 cm and standard deviation .1 cm. Machine 1 : Given mean = 3and standard deviation = 0.1. Acceptable corks have diameters between 2.9 cm and 3.1 cm. = P(2.9 x 3.1) x x = ( z ) Substitute x,and . = ( 2.93 z 3.13) 0.1 0.1 = ( 0.1 z 0.1) 0.1 0.1 = ( 1 z 1) P = 0.6826 Therefore first machine is 0.6826. The second machine produces corks...
