Using the dataset, produce a graph of per capita GDP for Argentina, China, and Canada from 1965 to 1995. Is inequality between these countries increasing? What is your evidence? Make sure that your argument full explains how to verify whether inequality between countries is increasing or not. Hint try using the code to produce the graph:
Two-way (line gdppc year if country=="Argentina", legend(label(1 "Argentina") label(2 "Canada") label (3 "China"))) (line gdppc year if country=="Canada") (line gdppc year if country=="China")
Then, make four scatter plots comparing per capita income in the year 2000 (on the Y-axis) to corruption, to political rights, to rule of law, and to socio-political instability. Note that these explanatory variables are "ordinal," meaning that we don't actually know what moving up one unit on, for example, the political rights scale means. All we know is that one level has more "rights' than another. What relationships come through in these plots? Which of the relationships appears to be the strongest? Formulate a hypothesis for why this relationship might be this strong. Report a multiple regression to see if your graphical interpretation of the strongest relationship is correct when controlling for other variables.

Calculate (rounded to the nearest tenth) The correlation between IQ and Anxiety r =??
A random sample of 15 paired observations has a correlation of -.46. Can we conclude that the correlation in the population is less than zero? Use the .05 significance level.
What is the probability that the sum of their scores exceeds 1200 and probability that the average of the scores of all 400 student
An old saying in golf is "you drive for show and you putt for dough." The point is that good putting is more important than long driving for shooting low scores and hence winning money.
Which of the following would have a binomial distribution and evaluate the binomial coefficient
Suppose that an IQ test was given to a large group of persons, the scores are assumed to be from a normally distributed population, that mean = 100 and s (standard deviation) = 15.
The data in the scatterplot below are an individual's weight and the time it takes (in seconds) on a treadmill to raise his or her pulse rate to 140 beats per minute. The o's correspond to females and the +'s to males.
The lifetime of a 2-volt non-rechargeable battery in constant use has a Normal distribution with a mean of 516 hours and a standard deviation of 20 hours. The proportion of batteries with lifetimes exceeding 520 hours is approximately.
