The chief of the emergency response services claims that their team responds to emergency distress calls within a 5 km radius in 360 seconds. An independent investigator wishes to test whether or not the presence of a thousand extra cars within the 5 km radius affects the emergency response time by 15.45 seconds. He randomly selects 100 distress calls and estimates the following regression: Ŷ₁ = 345 + 0.26X;, where ŷ, denotes the predicted response time measured in seconds for the ith emergency call and X; denotes the number of cars (in thousands) on the road within a 5 km radius at the time of the th emergency call. If ẞ₁ is the slope coefficient, which of the following options states the investigator's null and alternative hypotheses? ○ A. Hò: ß₁ >0.26 and H₁: ß₁ ≤0.26. B. Ho: B₁ =15.45 and H₁: B₁ #15.45. OC. Ho: B₁ =0.26 and H₁: B₁ #0.26. OD. Ho: B₁>15.45 and H₁: B₁ ≤15.45. Suppose act associated with the test the investigator wishes to conduct is 2.01. The p-value will be (Round your answer to three decimal places.) If the pre-specified significance level of the test was 5%, the calculated p-value suggests that we the null hypothesis.
