Please assist with a 5-step hypothesis test on the slope of a linear regression line. I have the scatter plot, line of best fit (including equation of the line). But I don't know how to test a hypothesis for the slope of a linear regression.
also explain if there is a 5-step hypothesis test for the correlation coefficient by any chance?
