Under what circumstances will the chi-square test for goodness of fit produce a large value for chi-square? ANSWER: to test hypotheses about the shape or proportions of a population distribution
F(2) = 20(1.25)^x
f(2) = 20(1.25)^2 - plug in 2 to x
f(2) = 20(1.5625) - calculate 1.25^2
f(2) = 31.25 - simplify
You would say 1/48=28/x and solve the proportion to get an answer of 1344 inches, which is 112 feet.
