Given:
2009 : 3,500 population
decrease of 2.2% per year.
100% - 2.2% = 97.8%
2014 - 2009 = 5 years
3,500 * (0.978)^5 = 3,500 * 0.89473 = 3131.57
The bird population in 2014 will be 3,131.57 or 3,132.
The data are bunched towards the higher values above the mean, but spread out to values below the mean. Therefore the median provides a better description of the center.

Answer:
0.125
Step-by-step explanation:
Cohen's d is used to measure the effect size. Larger the value of Cohen's d, larger the effect between two observations.
It is determined by the formula,

where M₂ is Mean of 1st group
M₁ is the Mean of the 2nd group.
Here, M₁ = 46, M₂ = 48 and Standard deviation = 16
∴ 
⇒ d = 0.125
