Recall the chapter example which described the fact that the mean IQ in large, diverse and the standard deviation is 15. Your sample of 300 members populations is 100 your community gave you a mean 99% confidence level for this sample. Which of the following your answer? the margin of error for the figures comes closest to 1Q score of 1os. Calculate t A. 10.95 B. ±1.96 C. 12.23 D. 11.16 E. None of the above

Given Information:  

Population size = n = 300

standard deviation = σ = 15

confidence level = 99%

Required Information:

Margin of error = ?

Step-by-step explanation:

The margin of error is a measure of the effectiveness of your survey.

Margin of error = z*(σ/√n)

z-score corresponding to 99% confidence level = 2.58

Margin of error = ±2.58*(15/√300)

Margin of error = ±2.58*(0.866)

Margin of error = ±2.23

Hence the correct option is C ±2.23

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 !
