Concerns about climate change and CO₂reduction have initiated the commercial production of blends of biodiesel (e.g., from renewable sources) and petrodiesel (from fossil fuel). Random samples of 48 blended fuels are tested in a lab to ascertain the bio/total carbon ratio.

(Round your answers to 4 decimal places.) The Interval Is from | to eBook (b) If the true mean Is .9050 with a standard deviation of 0.0100, what Is the sampling distribution of X ? Hint 1. Exactly normal with u = .9050 and o = 0.0100. 2. Approximately normal with u = .9050 and a = 0.0100. 3. Exactly normal with / = .9050 and oz = 0.0100 / v48. Ask 4. Approximately normal with / = .9050 and oz = 0.0100 / v/48. Print 01 02 References 03 04 (c) What theorem did you use to answer part (b)?
