Which of the following are feasible equations of a least squares regression line for number of dollars left in an endowment
providing college scholarships in each of its first ten years if it was entirely funded by a single donation?
X
That's not right.
O
y = 269,000 + 83003
O
= 69, 000 – 83003
O
y = –269,000 - 8300.0
O
= 269,000 - 83000
O
j = 0 - 83002

Don't know how to find x given these segment lengths

Put the equation in slope intercept form by solving for y

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
