A researcher is 95% confident that the interval from 19.7 posts to 27.3 posts captures u = the true mean amount of posts high school students make daily on social media.
Is there evidence that the true mean number of posts high school students make is less than 27?
O No. There is not evidence for the population mean to be less than 27, because 27 is within the 95% confidence
interval.
O No. There is not evidence for the population mean be less than 27, because there are values greater than 27
within the 95% confidence interval.
O Yes, there is evidence for the population mean to be less than 27, because 27 is within the 95% confidence
interval.
Yes, there is evidence for the population mean to be less than 27, because 27 is closer to the upper bound of the
95% confidence interval than the lower bound.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

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 !
