In the year 2000, the average car had a fuel economy of 22.74 MPG. You are curious as to whether this average is different from today. The hypotheses for this scenario are as follows: Null Hypothesis: = 22.74, Alternative Hypothesis: µ # 22.74. You %3D perform a one sample mean hypothesis test on a random sample of data and observe a p-value of 0.6901. What is the appropriate conclusion? Conclude at the 5% level of significance. 1) We did not find enough evidence to say the true average fuel economy today is greater than 22.74 MPG. 2) We did not find enough evidence to say the true average fuel economy today is less than 22.74 MPG. 3) The true average fuel economy today is significantly different from 22.74 MPG. 4) The true average fuel economy today is equal to 22.74 MPG. 5) We did not find enough evidence to say a significant difference exists hetween the true average fuel economy today and 22.74 MPG.

Question
In the year 2000, the average car had a fuel economy of 22.74 MPG. You are curious as to whether this average is different from today. The hypotheses for this scenario are as follows: Null Hypothesis: µ = 22.74, Alternative Hypothesis: µ + 22.74. You %3D perform a one sample mean hypothesis test on a random sample of data and observe a p-value of 0.6901. What is the appropriate conclusion? Conclude at the 5% level of significance. 1) We did not find enough evidence to say the true average fuel economy today is greater than 22.74 MPG. 2) We did not find enough evidence to say the true average fuel economy today is less than 22.74 MPG. 3) The true average fuel economy today is significantly different from 22.74 MPG. 4) The true average fuel economy today is equal to 22.74 MPG. 5) We did not find enough evidence to say a significant difference exists between the true average fuel economy today and 22.74 MPG.
