Amanufacturer is interested in the output voltage of a power supply used in a PC. Output voltage is assumed to be normally distributed with standard deviation 0.3 volt, and the manufacturer wishes to test Ho : u = 8 volts against Hiiu* & volts. Calculate the probability of a type Il error if the true mean output is 8.04 volts and round...

Surface roughness of steel is investigated. The method of surface manufacturing largely determines roughness of the surface. One of the parameters to describe the roughness is Rz, the maximum height of the surface irregularities profile. R (in um) is measured for 21 random places on the surface of forged details and 21 random places on the surface of casted details as follows....
