Question 2
Note: this question is somewhat difficult. You may need to follow along with video lecture 2.3 as you solve.
Recall that the index of dissimilarity is a way to categorize, numerically, how segregated a city is. Imagine a city comprised of 20 equal sized blocks, each with 10 residents. 5 blocks contain only rich people; 5 blocks contain only poor people; and ten blocks contain 40% rich people and 60% poor people. What is the index of dissimilarity? Your Answer | | Score | Explanation | 0.555 | | | | 0.0555 | ✔ | 1.00 | | 0.605 | | | | 0.1111 | | | | Total | | 1.00 / 1.00 | |
Question Explanation
Out of the 200 people in this city, the number of rich people equals (5∗10)+(10∗10∗0.4)=90.
The number of poor people equals (5∗10)+(10∗10∗0.6)=110.
For one block of all rich people, the contribution to the index of dissimilarity equals |1090−0110|=1090
For one block of all poor people, the contribution to the index equals |090−10110|=10110
For each of the other blocks, the contribution equals |490−6110|=199
Now we multiply the above results by the amount of blocks of each type:
(5∗1090)+(5∗10110)+(10∗199)=5090+50110+1099=1.111 Finally, we divide by 2: 1.1112=0.555
Therefore, the index of dissimilarity equals 0.555.

Question 3
Recall the standing ovation model. Suppose that for a particular show, perceptions of show quality are uniformly distributed between 0 and 100. Also suppose that individuals stand if they perceive the quality of the show to exceed 60 out of 100. Approximately what percentage of people will stand
