The Excel/Mega-Stat output given above summarizes the results of a one-way analysis of variance in an attempt to compare the performance characteristics of four brands of vacuum cleaners. The response variable is the amount of time it takes to clean a specific size room with a specific amount of dirt.
-At a significance level of 0.05,we would:

• A)Not be able to reject the null hypothesis of equal treatment group means.
• B)Reject the null hypothesis of equal treatment group means.
• C)Reject or fail to reject depending on the value of the t statistic.
• D)Not be able to decide whether or not to reject the null hypothesis due to insufficient information.
• E)Reject the significance level of the error term.
