A farmer is concerned that a change in fertilizer to an organic
variant might change his crop yield. He subdivides his six lots and
uses the old fertilizer on one half of each lot and the new
fertilizer on the other half. The following table shows the
results.
12
Using 5% significance level, which of the following is an
appropriate conclusion that supports or does not support the
farmer’s claim
choices :
A. Reject H0: µ = 0 and therefore do not conclude that the crop
yield with the new fertilizer is not significantly different from
the crop yield with the old fertilizer.
B. Do not reject H0: µ = 0 and therefore do not conclude that
the crop yield with the new fertilizer is not significantly
different from the crop yield with the old fertilizer.
C. Reject H0: µ = 0 and therefore conclude that the crop yield
with the new fertilizer is not significantly different from the
crop yield with the old fertilizer.
D. Do not reject H0: µ = 0 and therefore conclude that the crop
yield with the new fertilizer is not significantly different from
the crop yield with the old fertilize
