An inspector measures the diameter of ball bearings using a new type of caliper. The results were as follows (in mm): 0.265, 0.263, 0.266, 0.267, 0.267, 0.265, 0.267, 0.267, 0.265, 0.268, 0.268, and 0.263.
(a) Use the Wilcoxon signed-rank test to evaluate the claim that the mean ball diameter is 0.265 mm. Use α = 0.05.

what are the statements? and what do you mean by "216 2 1 6"?

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.

wait nvm i know the correct answer now its 100%   81 square feet
