10. plot the means of all six groups on a class dot plot.

Check the dot plot below

Step-by-step explanation:

1) Generally, a dot plot graph is made up based on a Spread Measure Graph (on Excel). A dot plot is a simple graph Used for discrete and continuous variables, whether for univariate or multivariate statistics.

In this question, we have a dot plot of six groups means, notice that group 3 and group 5 had the same measure. Some dot plots use axis between their dots, to connect their information.

2) Retrieving the data from this original questionnaire, we have this table (check it below)

3) Then from these data we can construct from a spread measure graph, a dot plot, just adjusting lines, and the dots.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
