Seven bags of rice from packing plant A were weighed and six

Seven bags of rice from packing plant A were weighed and six bags of the same rice and same size bags were weighed from packing plant b

plant A:29,22,25,36,31,28,31

plant B:33,35,32,25,26,27

Can we conclude that the variance of the bag weights from plant A are < the variance of the bad weights from plant B?

Using alpha=0.01, Can we conclude that the mean bag weight from plant A is equal to the mean bag weight from plant B?

Solution

we use F test here.

exel is ued to calculate the ts.

p value is >0.05, so we accept H0.

p>0.05, hence H0 is accepted.
