6. Two objects of unknown weights w, and w2 are weighed on an error-prone following way: (1) object 1 is weighed by itself, and the measurement is 3 g: (2) object 2 is weighed by itself, and the result is 3 g: (3) pan balance in the weight of object the difference of the weights (the weight of object 1 minus the ) is measured by placing the objects in different pans, and the result is 1 g: (4 the sum of the weights is measured as 7g. The problem is to estimate the true weights of the objects from these measurements.
esumated standard errors of the least squares estimates of part (b) e. Estimate wi - w2 and its standard error. f. Test the null hypothesis Ho: ww2

    Only do exerice 1-9 220AL-E1 he uncertainty in an experimental quantity must be reported. Since there are a number of ways to do this we must state the meaning of the uncertainty. A Estimated uncertaint Sometimes we make several measurements that are identical. Eq 1-2 would yield ơx-0, which could lead to the mistaken impression that the uncertainty is zero when in fact the precision of the instrument is less than the random errors. We must estimate the uncertainty, and,...
