Concerns about climate change and CO2 reduction have initiated the commercial production of blends of biodiesel (e. g., from renewable sources) and petrodiesel (from fossil fuel). Random samples of 35 blended fuels are tested in a lab to ascertain the bio/total carbon ratio. (a) If the true mean is 0.9480 with a standard deviation of 0.0060, within what interval will 95 percent of the sample means fall? (Round your answers to 4 decimal places.)
(b) If the true mean is 0.9480 with a standard deviation of 0.0060, what is the sampling distribution of X?
Choose an option below.
1. Exactly normal with μ=0.9480 andσ=0.0060.
2. Approximately normal with μ=0.9480 and σ=0.0060.
3. Exactly normal with μ=0.9480 and sigma^x=0.0060√35.
4. Approximately normal with μ=0.9480 and sigma^x=0.0060√35.
(c) What theorem did you use to answer part (b)?

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
