- Based on the last 300 UO Duck football games, the average points
scored by the opposition was 23 points with a dispersion of 7 points.
Therefore,
2/3 of the time that you attend a duck football game you would expect
the opposition to score between
- 23 and 30 points
- 16 and 23 points
- 16 and 30 points
- 23 and 37 points
- insufficient information to know

- Based on the Duck football game data, a 1 in 100 scoring event
by the opposition would be
- more than 23 points
- more than 30 points
- more than 37 points
- more than 41 points
- more than 45 points

- The grading scale in dispersion units on some midterm is
the following:
- > +2.00 --> A+
- 1.35 -- 2.00 --> A
- +0.95 -- 1.35 --> A-
- +0.50 -- 0.95 --> B+
- +0.20 -- 0.50 --> B
- -0.10 -- +0.20 --> B-
- -0.50 -- -0.10 --> C+
- -1.35 -- -0.50 --> C
- -2.00 -- -1.35 --> C-
- -2.30 -- -2.00 --> D+
- -2.70 -- -2.30 --> D

You take the midterm which had an average of 70 our of 120 points with a dispersion of 10 points. Your scored 55 points on the midterm. Your grade would therefore be:

- C+
- C
- C-
- D+
- D

- For that same midterm, to earn an A+ you would have to score more
than
- 90 points
- 95 points
- 100 points
- 110 points
- 115 points

- The Columbia River near Pasco has had about 100 years worth of flood
measurements made. Those data indicate a mean flood of +9.0 feet
with a dispersion of 5.0 feet around that mean. Based on this data
what would be the flood stage of a "1000" year flood?
- 9.0 feet
- 14.0 feet
- 19.0 feet
- 24.0 feet
- can't tell from the data given
