Suppose your manager indicates that for a normally distributed data set you are analyzing, your company wants data points between z
=
−
0.5
and
z
=
0.5
standard deviations of the mean (or within 0.5 standard deviations of the mean). What percent of the data points will fall in that range?
percent (Enter a number between 0 and 100, not 0 and 1 and round to 2 decimal places)

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
