Question 1173383
The mean is 1885.8 acres with sd=2456.3 acres
Ho: acres >=2000
Ha: acres < 2000
alpha=0.01
test stat is a t(0.99, df=4)=(x bar-mean)/s/sqrt(n)
critical value is t < -3.747
calculation is t=(-114.2)*sqrt(5)/2456.3=-0.10
fail to reject Ho. There is not sufficient evidence to reject the claim that they are at least 2000 acres.
