14. For the following sample of n = 6 scores: 0, 11, 5, 10, 5, 5
a. Sketch a histogram showing the sample distribution.
b. Locate the value pf the sample mean in your sketch, and make an estimate of the standard
deviation (as done in Example 4.6).
c. Compute SS, variance, and standard deviation for the sample. (How well does your
estimate compare with the actual value of s?).

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown
