QUESTION 1
A certain machine makes electrical resistors having a mean resistance of 50 ohms and a standard deviation of 4
ohms. Assuming that the resistance follows a normal distribution and can be measured to any degree of accuracy,
what percentage of resistors will have a resistance exceeding 47 ohms?
O 22.66%L
O 77.34%
O 42.47%
57.53%
QUESTION 2
A random sample of sizen= 100, from a population with standard deviation g=8 4 is used to test
HoiH=75 against H:u=79.5. We will reject Ho if
X>77
