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.

Bones Brothers & Associates prepare individual tax returns. Over prior years, Bones Brothers has maintained careful records regarding the time to prepare a return. The mean time to prepare a return is 90 minutes, and the population standard deviation of this distribution is 14 minutes. Suppose 100 returns from this year are selected and analyzed regarding the preparation time. What is the probability that the mean time for the sample of 100 returns for this year is greater than 92?
