The distribution of blood cholesterol level in the
populationof young men aged 20 to 34 years is close to normal with
meanu= 168mg/dl and standard deviation = 35 mg/dl. you measurethe
cholesterol level of 150 young men chosen at random andcalculate
the sampling mean.
a. if you did this many times, what would be themean and the
standard deviation of the distribution of the samplingmeans.
b. what is the probability that your sample has meanless than
165.

When constructing a perpendicular line through a point off a line, how can you verify that the lines constructed are perpendicular? check the angles used in the construction with a straightedge to ensure consistency. check the distance along the lines at several places with a compass to ensure they are the same length. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. check the distance between the lines at several places with a compass to ensure they are equidistant. question 2(multiple choice worth 1 points) (01.03 lc) which of the following steps is included in the construction of a perpendicular line through a point on a line? connect arcs that are above and below the given line with a straightedge. connect arcs that are above the original line with a straightedge. create arcs on either side of a point that is off the given line. create a copied angle by using the first two lines as the original angle.
