Random samples of 47 blended fuels are tested in a lab to ascertain the bio/total carbon ratio, (a) If the true mean is .9340 with a standard deviation of 0.0030, within what interval will 98 percent of the sample means fall? (Round your answers to 4 decimal places.) The interval is from to (b) If the true mean is .9340 with a standard deviation of 0.0030, what is the sampling distribution of X ? 1. Exactly normal with / = .9340 and a = 0.0030. 2. Approximately normal with /= .9340 and a = 0.0030. 3. Exactly normal with / = .9340 and of = 0.0030 /V47. 4. Approximately normal with = .9340 and of = 0.0030 /V47. 01 0 2 0 3 4 Prey 1 of 10 Next > 14 W
