Suppose that a recent poll found that 53% of adults believe that the overall state of moral values is poor. Complete parts (a) through (c). (a) For 300 randomly selected adults, compute the mean and standard deviation of the random variable X, the number of adults who believe that the overall state of moral values is poor. The mean of X is . (Round to the nearest whole number as needed.) The standard deviation of X is und to the nearest tenth as needed.) (b) Interpret the mean. Choose the correct answer below. O A. For every 300 adults, the mean is the range that would be expected to believe that the overall state of moral values is poor. O B. For every 300 adults, the mean is the minimum number of them that would be expected to believe that the overall state of moral values is poor. O C. For every 159 adults, the mean is the maximum number of them that would be expected to believe that the overall state of moral values is poor. OD. For every 300 adults, the mean is the number of them that would be expected to believe that the overall state of moral values is poor. (c) Would it be unusual if 159 of the 300 adults surveyed believe that the overall state of moral values is poor? O No Yes

Graph a triangle (xyz) and reflect it over the line y=x to create triangle xāyāzā. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point xā to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then yā with the reflecting line? how do you know?
