Using the sampling distribution shown in Figure 3.5(b), how likely are these sample means:

b.

(a) xÌ… = 70

(b) xÌ… = 100

(c) xÌ… = 140

Refer to the sampling distributions given in Figure 3.5. Several possible values are given for a sample statistic. In each case, indicate whether each value is (i) reasonably likely to occur from a sample of this size, (ii) unusual but might occur occasionally, or (iii) extremely unlikely to ever occur.
