An energy researcher wonders which type of heating—electric, natural gas, or oil—is the fastest in raising the temperature of a room. Eight different-sized rooms of identical construction are heated with each of the three types of energy source. Here are the times, in minutes, to raise the temperature by a given number of degrees:

a. State the H₀.

b. Prepare an ANOVA summary table of the results.

c. Write the results in APA format.
