Extracted text: An HP laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.57 ppm and a standard deviation of 3 ppm. Suppose that you draw a random sample of 11 printers.


Extracted text: Part iii) Consider the statement: 'The distribution of the mean printing speed of the sampled printers is Normal.' O A. It is a correct statement, and it is a result of the Central Limit Theorem. O B. It is an incorrect statement. The distribution of the mean printing speed of the sample is not Normal. O C.t is a correct statement, but it is not a result of the Central Limit Theorem.
