1. Use the REACTIONTIME data set. We want to see if the mean reaction time is faster for males than for females.
a. Using a = .05, go through the same steps as in problem #2. Be sure to make the necessary adjustment for this one-sided test.
b. Using the sample sizes and standard deviations from the PROC TTEST printout, calculate the pooled estimate of variance,.
2. Again use the REACTIONTIME data. We want to test, at a = .05, if the average reaction time is the same for the three types of stimuli.
a. In words (not symbols), write the null and alternative hypotheses.
b. Use PROC ANOVA to analyze this data, and include a corresponding Tukey multiple comparison procedure (use the LINES option). Turn in the printout.
c. State the p-value of the F-test, and state what we know only from this test.
d. Summarize the results of the Tukey multiple comparison procedure.
e. State MSERROR, and say what we can estimate with this. Be specific to this situation.

Milgram experiment continued to the full voltage
: Why is it that 68% of participants in the Milgram experiment continued to the full voltage. Why did they do something clearly immoral, something that thought was causing another human being extreme pain, just because they were instructed to do so?

Analyze the data using proc ttest
: Write the null and alternative hypotheses and analyze the data using PROC TTEST, and turn in the printout. From this, you will first have to test if the population variances are equal.

Derive an expression for the voltage across the inductor
: A 150 ohm resistor is connected in series with a 0.250 H inductor. The voltage across the resistor is VR = 3.80 cos (720t) Volts. Derive an expression for the voltage VL across the inductor
