Two shoemakers entered the competition, main goal of creating ten pairs of shoes, all sized
precisely at equivalent of Only precision of the size will be evaluated. The
following are the measurement of shoes' size:
Shoemaker A: ;
Shoemaker B:
In both cases, assume normality and have already tested at level of significance that
both shoemakers were successful and the mean values of size being equal to Further,
to test the overall punctuality, ie if the shoemakers are enough manually skilled to repeat
the correct size for every pair of shoes. Compare at significance level the deviation of
the size with a value of in shoemaker by onetailed test. Test if the variance in
shoemaker A is lower than in shoemaker B by a onetailed test.
