Construct a 95% prediction interval for y given x=2.5, y(hat) = -2.5x and se = 0.866. Round interval to three decimal places. x = -1,-2,-3,-4. y = 2,6,7,10. Please explain and if I can use one of the online regression calculators , please include. The answer should look like -15.566<y<3.066. Thanks.
