Serena says that if a regression line is drawn correctly in a scatterplot, there will always be the same number of points above
the line as there are below the line. Which of these must be a counterexample to her claim?
a scatterplot with an odd number of points in which the correct regression line passes directly through 0 of the points
a scatterplot with an even number of points in which the correct regression line passes directly through 0 of the points
a scatterplot with an odd number of points in which the correct regression line passes directly through 1 of the points
a scatterplot with an even number of points in which the correct regression line passes directly through 2 of the points

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
