The average mpg usage for a 2017 Toyota Prius for a sample of 23 tanks of gas was 45.6 with a standard deviation of 2.3. For a 2017 Ford Fusion, the average mpg usage for a sample of 23 tanks of gas was 44.0 with a standard deviation of 2.2.

Assuming equal variances, at= .05, is the true mean mpg lower for the Ford Fusion?

(a-1)Choose the appropriate hypotheses.

1. H₀:_toy-_ford 0 vs.H₁:_toy-_ford> 0. RejectH₀ift_calc> 1.680
2. H₀:_toy-_ford 0 vs.H₁:_toy-_ford> 0. RejectH₀ift_calc< 1.680
3. H₀:_toy-_ford 0 vs.H₁:_toy-_ford< 0. RejectH₀ift_calc< - 1.680
4. H₀:_toy-_ford 0 vs.H₁:_toy-_ford< 0. RejectH₀ift_calc> - 1.680

(a-2)Calculate thet_calc.(Round your answer to 4 decimal places.)

(a-3)Based on thet_calcdetermined, choose the correct decision: Fail to reject the null hypothesis or Reject the null hypothesis

(a-4)Is the true mean mpg lower for the Ford Fusion? Yes or No?
