A study was conducted to see if economic class was associated with the highest completed level of education. According to the study, 155 of 500 lower class adults obtained a bachelor’s degree or higher. This compares to 167 of 450 middle class adults who obtained a bachelor’s degree or higher. Assuming that the highest completed level of education does not depend on economic class, the probability of the data being the result of chance is calculated to be 0.05. Interpret this calculation.

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
