Question 1159195
variance is 10045, sd is 100.22
Ho: mean is 500 bushels
Ha: it isn't
alpha=0.05 p{reject Ho|Ho true}
test is a t (0.975 df=49)
reject if |t|>2.01
t=(x bar- mean)/s/sqrt(n)
=(-15*sqrt(50)/100.22
=-1.06
fail to reject Ho and there is insufficient evidence to state that the mean yield is not 500 bushels/acre
p=0.295
