Random samples of 48 blended fuels are tested in a lab to ascertain the bio/total carbon ratio. 5 points (a) If the true mean is .9050 with a standard deviation of 0.0100, within what interval will 90 percent of the sample means fall? (Round your answers to 4 decimal places.) The interval is from to eBook Hint (b) If the true mean is .)50 with a standard deviation of 0.0100, what is the sampling distribution of X ? Ask 1. Exactly normal with = .9050 and o = 0.0100. 2. Approximately normal with M - .9050 and o = 0.0100. Print 3. Exactly normal with J - .9050 and of = 0.0100 /V48. 4. Approximately normal with - .9050 and of = 0.0100 /148. References 1 3 (c) What theorem did you use to answer part (b)? . Central Limit Theorem Chebyshev's Theorem Pythagorean Theorem Grav
