You randomly survey students about year-round school. the results are shown in the graph.
a bar graph shows the percent of students who favor or oppose year-round school. the percent who oppose is 68 percent. the percent who favor is 32 percent. the error is plus or minus 5 percent.
the error given in the graph means that the actual percent could be 5% more or 5% less than the percent reported by the survey.
a. write and solve an absolute value equation to find the least and greatest percentages of students who could be in favor of year-round school. use $x$ as the variable in the equation.

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.
