Critical Thinking Suppose an x distribution has mean m 5 5. Consider two corresponding x distributions, the first based on samples of size n 5 49 and the second based on samples of size n 5 81.

(a) What is the value of the mean of each of the two x distributions?

(b) For which x distribution is P(x . 6) smaller?

Explain.

(c) For which x distribution is P(4 , x , 6) greater?

Explain.
