If the data in the table were entered into a regression calculator to produce a scatterplot and trend line, which window size would display all the points? x y 2 5 5 16 6 20 10 29 12 36 17 53 0 less-than-or-equal-to x less-than-or-equal-to 20; 0 less-than-or-equal-to y less-than-or-equal-to 50 0 less-than-or-equal-to x less-than-or-equal-to 20; 0 less-than-or-equal-to y less-than-or-equal-to 60 0 less-than-or-equal-to x less-than-or-equal-to 50; 0 less-than-or-equal-to y less-than-or-equal-to 20 0 less-than-or-equal-to x less-than-or-equal-to 60; 0 less-than-or-equal-to y less-than-or-equal-to 20

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
