What’s the equation of the regression line you’d use to predict stopping distance based on speed?
Answer:

Interpret the slope of the regression line.
Answer:

Find a 95% confidence interval for the slope of the regression line.
Answer:

Test the hypothesis H0: β1 = 0 and Ha: β1 ≠ 0.
Answer:

Suppose, instead of testing H0: β1 = 0, you decided to test H0: β1 = 5 against Ha: β1 ≠ 5. What P-value would be associated with this test?

From the given output the regression equation is

StopDist = ₋89.99 ₊5.7053(speed)

The slope of the regression equation is 5.7053

from the Excel output the 95% confidence interval for the slope of the regression line is (5.0809, 6.3296)

By the rejection rule ,reject the null hypothesis.

Given,

from the given output the regression equation is

StopDist = ₋89.99 ₊ 5.7053(speed)

Interpreting the slope of the regression line.

from the given output the regression equation the slope is 5.7053.

To find a 95% confidence interval for the slope of the regression line follow the excel procedure:

  1. click on the data>data analysis>Regression.
  2. In input Y range enter $B$2:$B$11
  3. In X range enter $A$2:$A$S11.
  4. Enter confidence level as 95.
  5. click on ok.

From the excel output the 95% confidence interval for the slope of the regression line is (50809, 6.3296).

State the hypothesis

Null hypothesis:

H₀ : β₁ ≠ 0

Alternative hypothesis:

Hₓ : β₁ ≠ 0

Reject rule:

If p value≤ α(=0.05), then reject the null hypothesis.

By the rejection rule, reject the null hypothesis (H₀)
