Question

question 9 of 10
when flipping a coin onto a table, it is very unlikely to land on its edge. what if you glued several pennies together and then flipped the stack? the students in mrs. chauvets statistics class collected data by repeatedly flipping stacks up to 27 pennies long. the scatterplot shows the relationship between number of pennies in the stack and edge percentage.
describe the relationship by selecting one description of direction, form, strength, and outliers.
there is a positive association between number of pennies and edge percentage.
there is a linear pattern in the scatterplot.
the association is strong.
there are several outliers with stacks of fewer than 5 pennies.
there is a negative association between number of pennies and edge percentage.
there is a nonlinear pattern in the scatterplot.
the association is weak.
there dont appear to be any points that depart substantially from the overall pattern.

Explanation:

Step1: Analyze the direction

As the number of pennies increases, the edge percentage also increases. So, there is a positive association.

Step2: Analyze the form

The scatter - plot does not follow a straight - line (linear) pattern. For example, the increase is not at a constant rate. So, it has a nonlinear form.

Step3: Analyze the strength

The points are somewhat spread out but still follow a general pattern. So, the association is not extremely strong but also not extremely weak. However, compared to a very weak association (where points are almost randomly scattered), it has a moderate - to - relatively - strong association.

Step4: Analyze outliers

There are no points that depart substantially from the overall pattern. The points with fewer pennies (less than 5) follow the initial part of the pattern (low edge percentage for low number of pennies)

Answer:

There is a positive association between number of pennies and edge percentage, there is a nonlinear pattern in the scatterplot, and there don't appear to be any points that depart substantially from the overall pattern.
