Suppose your manager indicates that for a normally distributed data set you are analyzing, your company wants data points between z
=
−
0.8
and
z
=
0.8
standard deviations of the mean (or within 0.8 standard deviations of the mean). What percent of the data points will fall in that range?

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
