One-Sample T: Salmon Weight
Test of mu = 40 vs mu > 40
Variable N Mean StDev SE Mean
Salmon Weigh 39 49.73 10.60 1.70
Variable 95.0% Lower Bound T P
Salmon Weigh 46.86 5.73 0.000
at 5% level of significance we have strong enough evidence to reject the Ho that the true mean weight of salmon is no different than 40 in favourof Ha that the true mean weight is significantly greater than 40.
