In testing a new drug, we obtained the following results:

Placebo Drug A Drug B Drug C
6 4 6 7
3 3 3 6
5 1 4 5
3 1 3 4
3 1 4 3

Run the ANOVA and fill in the summary table with the results obtained:

SS df MS F-ratio p-value
Between 3
Within 16
TOTAL

19

(Report P-value & F-ratio accurate to 3 decimal places and all other values accurate to 2 decimal places.)

What conclusion can be drawn at the 0.01 significance level?

A) The various drugs have results that are statistically different.

B)The various drugs do not have results that are statistically different.

We are testing a new prescription drug that cures the common cold. One of the side effects of the drug is insomnia (can’t sleep). There is a 6% chance the patient will develop insomnia. We have selected 50 people and administered the drug to them and asked if they developed insomnia. Define the random variable x to be the number of people who develop insomnia. Showing your work in Excel as demonstrated in class, what is the probability that x...

You are a graduate student testing a new drug (drug G) that reduces cocaine addiction in mice. You want to find out what the pharmacological action of drug G is, and you know that it involves monoaminergic signaling, but you don’t know more about it than that. You have found a monoaminergic synapse whose signaling is affected by drug G. You can stimulate the presynaptic neuron at this synapse and record the resulting EPSPs in the postsynaptic neuron. This synapse...
