The average daily volume of a computer stock in 2011 was muequals35.1 million shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of 40 trading days in 2014, he finds the sample mean to be 30.2 million shares, with a standard deviation of sequals13.5 million shares. Test the hypotheses by constructing a 95% confidence interval. Complete parts (a) through (c) below. (a) State the hypotheses for the test. Upper H 0: ▼ ▼ less than greater than not equals equals 35.1 million shares Upper H 1: ▼ mu sigma p ▼ less than equals not equals greater than 35.1 million shares (b) Construct a 95% confidence interval about the sample mean of stocks traded in 2014. The lower bound is nothing million shares. The upper bound is nothing million shares. (Round to three decimal places as needed.) (c) Will the researcher reject the null hypothesis? A. Do not reject the null hypothesis because muequals35.1 million shares falls in the confidence interval. B. Reject the null hypothesis because muequals35.1 million shares does not fall in the confidence interval. C.

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.
