Q2 - Expected and observed frequencies
It is beleived that a 6-sided dice is biased so that:
If you roll the dice 360 times, what is the expected frequency for each score?
P(1) = 0.1 P(2) = 0.15 P(3)= 0.05 P(4) = 0.2
P(5) = 0.2 P(6) = 0.3
Score | 1 2 3 4 5 6
expect| ***6 boxes are here**
-ed |
frenqu|
-ency |
—————————
In fact the observed frequencies are as follows:
Score 1. 2. 3. 4. 5. 6
Observed. 39 59. 17. 71. 78. 96
frequency
What does this tell you?
1. the model seems reasonable
2. the model is wrong
3. you need to buy a new dice
