Questions 6 to 12

A fourth grade class is studying the environment. One of their projects is to grow bean plants in 3 different soils.  100 plants each are planted in soil mixed with dryer lint, soil mixed with fertilizer and soil with nothing added.  At the end of the growing period, 5 plants from each soil type were measured (in inches) producing the data in the table below.  We will test the claim that there is no difference in mean bean plant height among each of the 3 soil types using a 5% significance level.  (Assume that independent samples were drawn from normal populations with equal variances.)

1.)What is the numeric
responsevariable?
