Textbook Question
Chapter 14.3, Problem 11P
This problem continues the Investigation of CIass Activity 10J in Section 10.2 on the size of your reflected face In a mirror. Flguro 14.49 shows a side view of a person looking Into a mirror. The mirror is parallel to line AE. Lines BF and DG are normal lines to the mirror
Figure 14.49 A side view of a person looking in a mirror
- What is the significance of the points F and G in Figure 14.49 ? Explain why. referring to the laws of reflection.
- Using the theory of congruent triangles discussed in this section, explain why triangles ABF and CBF are congruent and explain why triangles CDG and EDG are congruent.
- Use your answer to part (b) to explain why the length BD is half of the length AE. Therefore, explain why the reflection of your face in a mirror is half as long as your face’s actual length. (You may assume that BD and FG are the same length.)

•
Please Download "wages" from Canvas (the link to
this dataset is right below the HWA1 questions - it is
a Microsoft excel worksheet) and store it in your
favorite folder.
It contains 797 observations and 16 variables. The
"state" variable gives the names of the states
involved in this dataset.
• You need to have excel on your computer to open
this dataset.
i. You should use File > Import > Excel Spreadsheet
etc. as done in class 3 convert this file into a
Stata dataset. Once you are done, write the final
STATA code that makes the transformation of an
excel file to a STATA file possible.
ii. Write a code that will close the log file that has
been open since Question 1 part ii.
The mean, variance, skewness and kurtosis of a dataset are given as - Mean = 15, Variance = 20, SKewness = 1.5 and Kurtosis = 3.5 calculate the first four raw moments. (Note- Please include as much detailed solution/steps in the solution to understand, Thank you!)
