The National Opinion Research Center polled a sample of 92 people aged 18-22 in the year 2002, asking them how many hours per week they spent on the internet. The sample mean was 7.38, with a sample standard deviation of 12.83. A second sample of 123 people aged 18-22 was taken in the year 2004. For this sample, the mean was 8.20 with a standard deviation of 9.84.

Can you conclude that the mean number of hours per week increased between 2002 and 2004?

Use Alpha = 0.01.

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 !
