An HP laser printer is advertised to print text documents at a speed of 18 pm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.57 pm and a standard deviation of 3 pm. Suppose that you draw a random sample of 11 printers. Q) Consider the statement: 'The distribution of the mean printing speed of the sampled printers is Normal.' (Choice one of the following) 1) It is a correct statement, and it is a result of the Central Limit Theorem. 2) It is an incorrect statement. The distribution of the mean printing speed of the sample is not Normal. 3) It is a correct statement, but it is not a result of the Central Limit Theorem.

An HP laser printer is advertised to print text documents at a speed of 18 pm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.57 pm and a standard deviation of 3 pm. Suppose that you draw a random sample of 11 printers.
Q) Consider the statement: 'The distribution of the mean printing speed of the sampled printers is Normal.' (Choice one of the following)
1) It is a correct statement, and it is a result of the Central Limit Theorem.
2) It is an incorrect statement. The distribution of the mean printing speed of the sample is not Normal.
3) It is a correct statement, but it is not a result of the Central Limit Theorem.
