Question

Suppose that two attributes u and y both measures of net salt content have been recorded in wo different samples For each we wish to perform inference to their respective target populations Assume the populations are very large that our samples were realized by a method of random selection and that for both the normal model is appropriate Everything else equal if the variance of u is larger than that of y then Our calculated Cl for u will be wider than that for y Onone of these selections are correct Our calculated Cl for u will be the same as that for y Our calculated Cl for u will be narrower than that for y Everything else equal if the variance of u is 4 times smaller than that of y then Our calculated Cl for u will be 3 times wider than that for y Our calculated Cl for u will be 5 times wider than that for y Onone of these selections are correct Our calculated Cl for u will be 4 times narrower than that for y Our calculated Cl for u will be 10 times wider than that for y Our calculated Cl for u will be 2 times narrower than that for y
