test the hypothesis that the true slope of the regression line is zero (as opposed to nonzero). State the appropriate null and alternative hypotheses, give the value of the test statistic and give the appropriate P-value. (Use a significance level of 0.05.)

Create a class defined for Regression. Class attributes are data points for x, y, the slope and the intercept for the regression line.

Python:Create a class defined for Regression. Class attributes are data points for x, y, the slope and the intercept for the regression line. Define an instance method to find the regression line parameters (slope and intercept). Plot all data points on the graph. Plot the regression line on the same plot.

There is a regression line Y = 10 + 11X. The SEE for the slope is 60. The sample size is 10. The standard deviation of Y is 100 and the standard deviation of X is 5. Do a hypothesis test. Calculate the t-statistic, state the critical value, and state what this means with regards to the relation between X and Y.
