Find the interval [,.L U+ Z in J within which 95 percent of the sample means would be expected to fall, assuming that each g Z _ Vi G sample is from a normal population. (a) u=161, 0=12, n=47. (Round your answers to 2 decimal places.) The 95% range is from (b) u=1,317, o= 21, n=10. (Round your answers to 2 decimal places.) The 95% range is from (c) L=70, o=1, n=27. (Round your answers to 3 decimal places.) The 95% range is from Concerns about climate change and CO5 reduction have initiated the commercial production of blends of bicdiesel (e.g., from renewable sources) and petrodiesel (from fossil fuel). Random samples of 44 blended fuels are tested in a lab to ascertain the bio/total carbon ratio. (a) If the true mean is .9590 with a standard deviation of 0.0080, within what interval will 98 percent of the sample means fall? (Round your answers to 4 decimal places.) The interval is from
