Question
The table below shows the gas mileages (in miles per gallon) of eight cars with and without using a fuel additive. At α = 0.10, is there enough evidence to conclude that the fuel additive improved gas mileage? | Car | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | |----------------------------|-----|-----|-----|-----|-----|-----|-----|-----| | Gas mileage without additive | 23.4 | 24.2 | 21.6 | 20.6 | 25.2 | 23.4 | 25.1 | 25.3 | | Gas mileage with fuel additive | 26.6 | 25.5 | 24.3 | 22.0 | 26.1 | 24.9 | 26.1 | 25.2 | Identify the claim and state H₀ and H₃. The claim is "The fuel additive \(\underline{\text{improves}}\) gas mileage." Let μᵈ be the hypothesized mean of the cars' gas mileage without additive minus their gas mileage with additive. State H₀ and H₃. Choose the correct answer below. A. - H₀: μᵈ ≠ 0 - H₃: μᵈ = 0 B. - H₀: μᵈ ≥ 0 - H₃: μᵈ < 0 C. - H₀: μᵈ ≤ 0 - H₃: μᵈ > 0 D. - H₀: μᵈ = 0 - H₃: μᵈ ≠ 0 E. - H₀: μᵈ = 0 - H₃: μᵈ > 0 F. - H₀: μᵈ ≤ 0 - H₃: μᵈ > 0 Calculate \( \bar{d} \) and \( s_d \). \( \bar{d} = \) (Type an integer or a decimal.
