Answer:
x ≤ 35/8
Step-by-step explanation:
1. move the constant to the right
2. Calculate 8x ≤ 56-21
3. Divide 8 from 8x ≤ 35
x ≤ 35/8

The odds ratio for birds having long beaks being able to fly against birds not having long beaks being able to fly is 3.76.
<h3>What is an odds ratio?</h3>
An odds ratio is a measure of the strength of an association with the exposure and outcome.
The odds ratio can be calculated by dividing the odds of the first group (exposure) by the odds of the second group (outcome).
Flies Does not fly Total
Long beak 11 7 19
Not a long beak 3 13 15
Total 14 20 34
Probability of long beaks flying = 0.79 (1/14)
Probability of not having long beaks flying = 0.21 (3/14)
Odds ratio = 3.76 (0.79/0.21)
Thus, the odds ratio for birds having long beaks being able to fly against birds not having long beaks being able to fly is 3.76, showing greater odds of association.
