A2006 poll asked whether turkey should be included in the european union if it met all conditions set by the eu. 51% of respondents from denmark said "yes". identify the point estimate and the 95% confidence interval. then, draw substantive conclusions about the danish population based on this poll.

Step-by-step explanation:

Hello!

Your study variable is

X: number of danish that supports the inclusion of Turkey to the EU, of a sample of n people.

This is a discrete variable. It has only two possible outcomes "yes" and "no" and what is of interest is the proportion of danish that voted yes on the poll. (success) The sample size n is fixed since the beginning, the proportion of success is the same from one trial to another and the trials are independent of trial to trial.

The parameter is the population proportion ρ

Its point estimate is the sample proportion ^ρ

If you take the n danish that answered the 2006 poll as the sample, then the sample proportion is ^ρ= 0.51

Applying the Central Limit Theorem you can approximate the sample proportion distribution to normal, and use the Z-statistic to estimate the population proportion with a Confidence Interval.

Z=       ^ρ - ρ     ≈N(0;1)

     √(^ρ(1-^ρ))/n

The formula for the interval:

^ρ ± *√(^ρ(1-^ρ))/n

Suppose the sample size was n= 500

The Confidence Interval is:

^ρ ± *√(^ρ(1-^ρ))/n

= = 1.96

0.51 ± 1.96*√(0.51(1-0.51))/500

[0.4562; 0.5538]

With a Confidence level of 95%, you'd expect that the population proportion of danish that supports Turkey entering the EU is contained by the interval [0.4562; 0.5538].

I hope it helps!

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
