As a member of the marketing team for a pasta manufacturer, you want to find out whether there's any difference in the mean number of people who would buy the new macaroni product, L-Bow Roni, if it had a red box if it had a blue box. In each session, you bring in 30 people to try L-Bow Roni and have them respond with whether they would buy this product over the competitor's product. Suppose you conducted 45 sessions with the red box and 60 sessions with the blue box. This data sheet gives you the number of yes responses to the survey for each session.

Note that the two samples are different sizes.

To determine whether this difference is significant, you need to find the standard deviation of the sample mean differences. For this task, you'll use this formula for the standard deviation of sample mean differences.

(See the photo I inserted for the formula)

In this formula, the subscripts M1 and M2 represent the means of the two samples, and are the standard
deviations of the two populations, and n1 and n2 are the sample sizes.

Part A

Use the spreadsheet's Average function (look under AutoSum in the Function menu) to calculate the
means.

Enter the correct value in each box. Use numerals instead of words, and round each value to the nearest hundredth.

The mean value of people who would purchase the red box is -.
The mean value of people who would purchase the Blue box is -.

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.
