Solution :
It is given that the mean and the standard deviation for a sample of 24 domestic cars is 35.696 MPG and 4.931 MPG respectively and the mean and the standard deviation for a sample of 16 cars is 34.345 MPG and 7.118 respectively.
The 90% confidence level for the men difference between the two samples is (-2.906, 2.844).
We know that the confidence interval is calculated to determine the mean difference among the two samples with the specified level of confidence.
Therefore, we can say that with 90% confidence, we have the 90% chances that the true mean differences will be within the range of -2.906 MPG to 2.844 MPG.
Thus, it is required 90% confidence interval interpretation.
The answer to represent a check for 10$ is A. -10
Answer:
9
Step-by-step explanation: 18-9=9
The answer is mean absolute deviation
Answer:
Linear pair angle of 40 is
=180-40
=140
If, the two rays are parallel
Therefore, the two rays are parallel and the straight line is transversal
Therefore, (?) angle =140 corrosponding angle
Your answer is 140
