The effect of acid rain upon the yield of crops is of concern in many places. In order to determine baseline yields, a sample of 13 fields was selected, and the yield of barley (g/400m2) was determined. The output from SAS appears below:

CV 26.5958 STD MEAN 16.245 1% 161 205 392
A 95% confidence interval for the mean yield is:
a.220.2 ± 1.96(58.6)
b.220.2 ± 1.96(16.2)
c.220.2 ± 2.18(58.6)
d.220.2 ± 2.18(16.2)
220.2 ± 2.16(16.2)
