A researcher compares two compounds (1 and 2) used in the manufacture of car tires that are designed to reduce braking distances for SUVs equipped with the tires. SUVs equipped with tires using compound 1 have a mean braking distance of 45 feet and a standard deviation of 11.6 feet. SUVs equipped with tires using compound 2 have a mean braking distance of 49 feet and a standard deviation of 6.1 feet. Suppose that a sample of 76 braking tests is performed for each compound. Using these results, test the claim that the braking distance for SUVs equipped with tires using compound 1 is shorter than the braking distance when compound 2 is used. Let μ1μ1 be the true mean braking distance corresponding to compound 1 and μ2μ2 be the true mean braking distance corresponding to compound 2. Use the 0.1 level of significance.
Step 1 of 4: State the null and alternative hypotheses for the test.
Step 2 of 4: Compute the value of the test statistic. Round your answer to two decimal places.
Step 3 of 4: Determine the decision rule for rejecting the null hypothesis H0. Round the numerical portion of your answer to two decimal places.
Step 4 of 4: Make the decision for the hypothesis test. Fail or reject to fail.
Step 2 of 4 :
Compute the value of the test statistic. Round your answer to two decimal places.

For this question you are not allowed to use the lm() command in R or the equivalent of lm() in python or other software. If you want to use a software, only use it as a calculator. So if you are using R, you may only use mean(), sum(), qt() and of course +,-,*,/. (Similar restrictions for Python, excel or others).
Consider all the 27 numbers printed under Group1 and Group2 as your y values, and the two group indicators as a categorical variable x ( indicating Group1 vs Group2).
(a) Fit a least square regression line and calculate the intercept and the slope.
(b) At 5% level of significance, test that the true slope parameter is zero.
(c) Match your answer from part (b) to your answers from Question 2. Describe briefly any similarity that you see.
