Slope Confidence Interval

Problem

A symmetric confidence interval for a slope is [b - t * se, b + t * se], where t is the critical value for the desired level.

Given the slope, its standard error, and the critical value, return [lower, upper].

Hint

Center the interval at the estimate.

case 1

in: [2,0.5,2]

expected: [1,3]

case 2

in: [0,1,1.96]

expected: [-1.96,1.96]

case 3

in: [-3,0.1,2.576]

expected: [-3.2576,-2.7424]
