16Filling off standard; stop and adjust machine
The sample size is 34 and the population standard deviation is= 0.6. Use= .05. Do not round intermediate calculations.
a. What would a Type II error mean in this situation?
b. What is the probability of making a Type II error when the machine is overfilling by .5 ounces (to 4 decimals)?
c. What is the power of the statistical test when the machine is overfilling by .5 ounces (to 4 decimals)?
