Step 4: Save this dataset and next use the insheet command to read in dataset_2_gdp.csv which is also available on the course website (/Assignments/STATA Pset 1/). Step 5: Give the variable gdp_percap_ppp_2011 a label. In particular, label it "GDP per capita, PPP (constant 2011 international \$)". Step 6: Use the browse command to see what gdp_percap_ppp_2011 contains. Use the replace command to replace all instances of ".." with a blank instead. Step 7: Use the summarize command to compute the number of observations, mean and standard deviation of the gdp_percap_ppp_2011 variable and write these down. Hint: Sometimes, the data is in a string format rather than a numerical format. You will need to use the destring command to convert this string into a numerical variable
