stimate the same regression, excluding the data from Malta. Answer the same question in (c). e) Plot the estimated regression functions from (c) and (d). Using the scatterplot in (a), explain why the regression function that includes Malta is steeper than the regression that excludes Malta. f) Where is Malta? Why is the Malta trade share so large? Should Malta be included or excluded from the analysis? Please just answer the remaining quest
On the text website, http://www.pearsonhighered.com/stock_watson/, you will find the data file Growth, which contains data on average growth rates from 1960 through 1995 from 65 countries, along with variables that are potentially related to growth. A detailed description is given in Growth_Description, also available on the website. In this exercise, you will investigate the relationship between growth and trade.
a) Construct a scatterplot of average annual growth rate (Growth) on the average trade share (TradeShare). Does there appear to be a relationship between the variables? Have been answered before by bartleby
b) One country, Malta, has a trade share much larger than the other countries. Find Malta on the scatterplot. Does Malta look like an outlier? Have been answered before by bartleby
c) Using all observations, run a regression of Growth on TradeShare. What is the estimated slope? What is the estimated intercept? Use the regression to predict the growth rate for a country with a trade share of 0.5 and for another with a trade share equal to 1.0. Have been answered before by bartleby
d) Estimate the same regression, excluding the data from Malta. Answer the same question in (c).
e) Plot the estimated regression
f) Where is Malta? Why is the Malta trade share so large? Should Malta be included or excluded from the analysis?
Please just answer the remaining questions as suggested by bartleby expert earlier. Thanks
