In September 2011, Gallup surveyed 1,004 American adults and asked them whether they blamed Barack Obama a great deal, a moderate amount, not much, or not at all for U. S. economic problems. The results showed that 53% of respondents blamed Barack Obama a great deal or a moderate amount.
(a) Calculate the 99% confidence interval for the proportion of all American adults who blame Barack Obama a great deal or a moderate amount for U. S. economic problems.
(b) Does the confidence interval indicate that a majority of all American adults blame Barack Obama a great deal or a moderate amount for U. S. economic problems?

a) Yes, because the entire interval is above 0.5.
b) Yes, because 53% is a majority.
c) No, because a sample of 1004 adults can’t tell us about the entire population.
d) No, because the interval extends below 0.5, meaning that it is reasonably possible that a minority of all American adults feel this way.

it is c, trust i got your back lol

step-by-step explanation:

step-by-step explanation: 4 cause 2+2=4

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 !
