Suppose that you are attempting to buy a house, and you are bargaining with the current owner over the sale price. The house is

katen-ka-za [31]

Answer:

the answer is to make the first offer!

Step-by-step explanation:

Since the surplus ($100000) is rapidly depleting, and though the second individual collects the whole surplus, it is already less than half of the surplus from the previous day. So, once you make the first bid, any offer above 100,000 would be fair to the second person and if he rejects the offer, he will only be able to get 100,000 the next day. You will raise the payout by 100000(1 ) this way.

The Regression Equation Suppose in this semester, our Exam 1 average was about 85 with an SD of about 12. Suppose the correlatio

kirill [66]

Answer:

0.410

Step-by-step explanation:

We are predicting exam 2 scores from exam 1 scores so the dependent variable y is exam 2 scores and independent variable is exam 1 scores x.

The regression equation is

y=a+bx

Where y is exam 2 scores and x is exam 1 scores.

We are given that

correlation coefficient=r=0.6.

Mean and standard deviation of x are xbarx=85 and Sx=12.

Mean and standard deviation of y are xbary=82 and Sy=8.2.

The slope b for this scenario can be found as

$slope=b=r\frac{Sy}{Sx}$

$slope=b=0.6(\frac{8.2}{12} )$

$slope=b=0.6(0.6833)$

$slope=b=0.41$

Thus, the slope of the regression equation for predicting Exam 2 scores from Exam 1 scores is 0.410.
