Increased value accumulates on a tax-free basis until funds are withdrawn. C. Early withdrawals are penalty free if spent on living expenses. D. Withdrawals are tax free upon retirement.

[Done] The information in the table represents the effect of the mass of two objects on the gravitational force between the two objects. | Mass of Object 1 (kg) | Mass of Object 2 (kg) | Distance between Objects 1 and 2 (m) | Gravitational Force between Objects 1 and 2 (N) | |---|---|---|---| | 1 | 1 | 1 | 4 | | 2 | 1 | 1 | ? | Which number should be in the cell with the question mark? A. The number is two because when you double the mass of one of the objects, the force between the objects is halved. B. The number is four because when you double the mass of one of the objects, the force between the objects remains the same. C. The number is eight because when you double the mass of one of the objects, the force between the objects also doubles. D. The number is sixteen because when you double the mass of one of the objects, the force between the objects

[Done] A researcher has constructed the following ANOVA table. Some numbers are left blank for you to figure out. | Source | SS | DF | MS | F | p-value | | :----- | :---- | :- | :----- | :---------- | :---------- | | Factor | | 3 | 45 | --------- | ---------- | | Error | 337 | 12 | | | | | Total | 472 | | | | | Answer the following questions. (d) What's the p-value? (e) What should be the conclusion? A. < 0.05; We reject [tex]$H _0$[/tex]. We conclude that the four group means are significantly different. B. > 0.05; We do NOT reject [tex]$H _0$[/tex]. We conclude that the four group means are NOT significantly different. C. > 0.05; We reject [tex]$H _0$[/tex]. We conclude that the four group means are significantly different. D. < 0.05; We do NOT reject [tex]$H _0$[/tex]. We conclude that the four group means are NOT significantly different.
