Do the two drugs differ significantly with regard to their effect in increasing weight? (The table value of t for d.f. 10 at 5% level-2.23).

4. What is time series analysis? Decompose a time series into its various components and describe them.

5. What is a random variable? How is it used to define a probability distribution? Make the probability distribution of "scores facing up" in a throw of two dice.
