The distribution of annual earnings of all bank tellers with five years of experience is
skewed negatively. This distribution has a mean of Birr 15,000 and a standard deviation
of Birr 2000. If we draw a random sample of 30 tellers, what is the probability that their
earnings will average more than Birr 15,750 annually?
Required:
 Calculate μ and
x

 Calculate Z for X
 Find the area covered by the interval
 Interpret the results
