Suppose that you are interested in estimating the ceteris paribus relationship between y and x1. for this purpose, you can collect data on two control variables, x2 and x3. (for concreteness, you might think of y as final exam score, x1 as class attendance, x2 as gpa up through the previous semester and x3 as sat or act score). let β˜ 1 be the simple regression estimate from y on x1 and let βˆ 1 be the multiple regression estimate from y on x1, x2, x3. (a) if x1 is highly correlated x2 and x3 in the sample and x2 and x3 have large partial effects on y, would you expect β˜ 1 and βˆ 1 to be very similar or very different? explain. (b) if x1 is almost uncorrelated with x2 and x3, but x2 and x3 are highly correlated, will β˜ 1 and βˆ 1 tend to be similar or very different? explain. (c) if x1 is highly correlated with x2 and x3, and x2 and x3 have small partial effects on y, would you expect se[ β˜ 1] or se[βˆ 1] to be smaller? explain.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

idk

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 !
