An Experimenter Was Interested in the Effect of Expectations and Drugs

An experimenter was interested in the effect of expectations and drugs on time perception. She gave participants either an amphetamine (a stimulant) or a placebo (an inert substance) and told them that they had received a stimulant or told them that they had received a depressant. The design looks like this: $$\begin{array} { l c l l } \text { Actually Received } & { \text { Told They Received } } & \\& { \text { Stimulant } } & \text { Depressant } & \\\text { Stimulant } & \sum \mathrm { X } = 205 & \sum \mathrm { X } = 89 & \\& \Sigma \mathrm { X } ^ { 2 } = 6000 & \sum \mathrm { X } ^ { 2 } = 1150 & \\\text { Placebo } & \sum \mathrm { X } = 195 & \sum \mathrm { X } = 37 & \\& \Sigma \mathrm { X } ^ { 2 } = 5500 & \sum \mathrm { X } ^ { 2 } = 283 & N = 8 \text { per cell }\end{array}$$ The score each participant received was a composite of several time-perception measures. Higher scores mean that time perceived as passing more quickly than it is. Perform an ANOVA with $\alpha$ = .05 and interpret the results. Include a summary table.
