Show transcribed image text For the remaining questions, consider the following experimental setup: Mice were injected with the following substances (saline as a placebo, clenbuterol as a treatment, and clenbuterol+ propranolol as another treatment). Clenbuterol is supposed to activate beta receptors and propranolol is supposed to block the effects of clenbuterol. Their brains were removed one hour later and tested for concentrations of tryptophan (units = ng/ml). The significance level was set at 0.05.
