a. Make a decision regarding Ho
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! Ho: salary is $26,000
Ha: it isn't
alpha is 0.05
test statistic is a t df=9, 0.975=2.262
reject if |t|>2.262
t=(x bar-26000)/s/ sqrt (10)
t=(25852.2-26000)*sqrt(10)/3197.08
=-0.146,
Fail to reject Ho.
Insufficient evidence to conclude that the mean is not $26,000.
