correct answer will get 10 points? No, because the two confidence intervalsâ€‹ overlap, we cannot conclude that the two population means are different.44An IQ test is designed so that the mean is 100 and the standard deviation You can only upload a photo (png, jpg, jpeg) or a video (3gp, 3gpp, mp4, mov, avi, mpg, mpeg, rm).

No, because the proportion could easily equal 0.5. Can we conclude that the population means formales and females areâ€‹ different? The sample measures a quantitative value. Research from other sources suggests that the population of weights of women has a standard deviation given by Ïƒ = 32.99 lb.
