Question: Solve fast The population linear regression line is given as y = A + Bx + 8. A simple linear regression model for a sample

Solve fast

The population linear regression line is given as y = A + Bx + 8. A simple linear regression model for a sample size of 15 relating temperature (x) to a lifetime of motors (y) obtained is y = -0.9754 + 0.2553x. It is known that the 90% confidence interval for the sample slope is (0.1850, 0.5350). Analyse the hypothesis for the slope by providing the following information: a. Calculate s . the standard deviation of the slope. b. Examine the hypothesis that the population slope, B, is greater than 0.2 at a 0.5% significance level
