3)   A frequency distribution that is bell-shaped, symmetrical, and unimodal is ____.

4)   A frequency distribution that has a tail trailing off to the right of the distribution is ________________.

5)   A frequency distribution of ages of residents at a senior citizen home is clustered around 83 with a long tail to the left. This distribution is _______________.

6)   When a variable cannot take on values above a certain level, this is known as a(n) __________ effect.

7) )  A grouped frequency table has the following intervals: 30–44, 45–59, and 60–74.

8) Do the data below show a linear relation, non-linear relation, or no relation at all?

9) Do the data below show a linear relation, non-linear relation, or no relation at all?

Part I:

Question 10a- 10e

10-a)    In which of the four boroughs is the median household income highest? (This is made evident as you click on the different lines.)

10-c)     Click on line 2. Which borough (not a street) shows the least variability in median household income?

10-d)     On line 2, find the following two subway stops: Park Place (the first of the highest Manhattan stops) and E 180 St. (one of the lowest Bronx stops, located about halfway across the BRX section). What is the difference (calculate) between the median household incomes of the two areas?
