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

Figure 3.5

c.

(a) xÌ… = 250

(b) xÌ… = 305

(c) xÌ… = 315

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,

(iii) Extremely unlikely to ever occur.
