An experiment was conducted to see the effectiveness of twoantidotes to three different doses of a toxin. The antidote wasgiven to a different sample of participants five minutes after thetoxin. Twenty-five minutes later the response was measured as theconcentration in the blood. What can the researchers conclude withα = 0.01?

a) What is the appropriate test statistic?
---Select--- na one-way ANOVA within-subjects ANOVA two-wayANOVA
b) Compute the appropriate test statistic(s) tomake a decision about H0.
Antidote: critical value =Â Â ; teststatistic =
Decision:Â Â ---Select--- Reject H0 Fail to reject H0
Dose: critical value =Â Â ; test statistic=
Decision:Â Â ---Select--- Reject H0 Fail to reject H0
Interaction: critical value =Â Â ; teststatistic =
Decision:Â Â ---Select--- Reject H0 Fail to reject H0
