A coffee machine is adjusted to provide a population mean of 100 [ml] of coffee per cup and a standard deviation of 3 (ml]. The volume of coffee per cup is assumed to have a normal distribution. The machine is checked periodically by sampling 5 cups of coffee. If the mean volume, , of those 5 cups in [ml] falls in the interval (100 – 20,) <ĩ < (100 + 20, ), no adjustment is made. Otherwise, the machine is adjusted. If a 5-cup test gives a mean volume of 97.0 [ml), the machine needs to be adjusted. O True O False Question 13 3 pts R=C,+C,4+C B+C,AB+error is one of the mathematical models used to represent the relation between the response R and factors A and B. In the equation, C,C. C., and C, are constants. Since there is an interaction between factors A andB, the factorial design cannot be used in experimentation.
