Many scientists have warned that global warming is causing the polar ice caps to melt and, therefore, sea levels around the world to rise. 415 random samples of the sea level (in millimeters) at Rockport, Massachusetts, from 1987 to 2011 were obtained and are summarized in the following table. The level was measured to the nearest millimeter.

Class	Frequency	Relative Frequency
1400 - 1600	4
1600 - 1800	42
1800 - 2000	190
2000 - 2200
2200 - 2400	15
2400 - 2600	3
2600 - 2800	2
Total	415

Blank 1: Calculate the frequency for 2000-2200 class. Blank 2: Calculate the relative frequency for 2000-2200 class. (Please include 4 decimal places) Blank 3: What is the relative frequency for the row of total?
