Flavia was curious if a sample first quartile lor Q1) was an unbiased estimator of a population first quartile She started with a large normally distributed population of test scores whose first quartile was Q1 = 70 points. She then took a random sample of 6 tests and calculated the first quartile of the sample. She replaced those tests and repeated this process for a total of 50 trials. Her results are summarized in the dotplot below, where each dot represents the first quartile from a sample of 6 tests. 60 61 68 72 Sample first quartile 76 80 Based on these results, does sample first quartile appear to be a blased or unbiased estimator of 6 of 9

its 4 because 2 times 2 is 4, if you double the number two you get four

answer: sine

step-by-step explanation:

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 !
