Apply STATA commands & submit the output for each question
only when indicated below
i. Apply the command egen to create a variable called "wyd"
which is the rowtotal function on variables bwght & faminc.
ii. Apply the list command for the first 10 observations to
show that the code in part i worked. Include the outcome of
this code
iii. Apply the egen command to create a new variable called
"bwghtsum" using the sum function on variable bwght by
the variable high_faminc (Note: need to apply the bysort'
statement)
iv. Apply the "by high_faminc" statement to find the
V.
descriptive statistics of bwght and bwghtsum Include the
output of this code.
Why is there a difference between the standard deviations
of bwght and bwghtsum from part iv of this question?
According to a health information website, the distribution of adults’ diastolic blood pressure (in millimeters of mercury, mmHg) can be modeled by a normal distribution with mean 70 mmHg and standard deviation 20 mmHg.
b. Above what diastolic pressure would classify someone in the highest 1% of blood pressures? Show all calculations used.
Write STATA codes which will generate the outcomes in the questions

Write a code which will allow STATA to go to your favorite folder
to access your files. Load the birthweight1.dta dataset from your
favorite folder and save it under a different filename to protect
data integrity. Call the new dataset babywt.dta (make sure to use
the replace option).
Verify that it contains 2,998 observations and 8 variables. Include
the output of this code.
Are there missing observations for variable(s) for the variables
called bwght, faminc, cigs? How would you know? (You may use
more than one code to show your answer(s)) Include the output
of your code (s).
Write the definitions of these variables: bwght, faminc, male,
white, motheduc,cigs; which of these variables are categorical?
