Hey, please help me answer the following problems:

Question 1 Suppose that two attributes, w and v, both measures of "net likes", have been recorded in two 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 w is larger than that of v, then Onone of these selections are correct O Our calculated Cl for w will be wider than that for v O Our calculated Cl for w will be narrower than that for v OOur calculated Cl for w will be the same as that for v Everything else equal, if the sample size of w is 16 times smaller than that of v, then OOur calculated Cl for w will be 2 times narrower than that for v O Our calculated Cl for w will be 4 times narrower than that for v O Our calculated Cl for w will be 5 times narrower than that for v O Our calculated Cl for w will be 10 times narrower than that for v Our calculated Cl for w will be 4 times wider than that for v Onone of these selections are correctQuestion 2 Suppose that two attributes, u and y, both measures of "net salt content", have been recorded in two 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 sought confidence level of u is greater than that of y, then O Our calculated Cl for u will be wider than that for y Our calculated Cl for u will be the same as that for y Onone of these selections are correct O Our calculated Cl for u will be narrower than that for y Everything else equal, if the sample size of u is 16 times larger than that of y, then O Our calculated Cl for u will be 3 times wider than that for y Our calculated Cl for u will be 3 times narrower than that for y Onone of these selections are correct Our calculated Cl for u will be 2 times wider than that for y O Our calculated Cl for u will be 10 times wider than that for y OOur calculated Cl for u will be 4 times narrower than that for yQuestion 3 Suppose that two attributes, wand y, both measures of "net salt content", have been recorded in two 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 w is smaller than that of y, then O Our calculated Cl for w will be narrower than that for y Onone of these selections are correct O Our calculated Cl for w will be wider than that for y O Our calculated Cl for w will be the same as that for y Everything else equal, if the variance of w is 100 times smaller than that of y, then O Our calculated Cl for w will be 5 times narrower than that for y Onone of these selections are correct O Our calculated Cl for w will be 10 times narrower than that for y Our calculated Cl for w will be 3 times wider than that for y Our calculated Cl for w will be 3 times narrower than that for y O Our calculated Cl for w will be 5 times wider than that for y
