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

(b) What is the difference of the sample means of those who would purchase the red box and those who would purchase the blue box?

1.39
1.86
1.74
2.08
Part C
Question
Use the standard deviation values of the two samples to find the standard deviation of the sample mean differences.

Sample Standard Deviation
red box 3.868
blue box 2.933
Then complete each statement.

The sample size of the session regarding the number of people would purchase the red box, , is
.

The sample size of the session regarding the number of people would purchase the blue box , , is
.

The standard deviation of the sample mean differences is approximately

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

umm you say your want to . but you do know that this is the mathematics.
