Putting the values, we get:

b) Interpretation of confidence interval:
We are 90% confident that the true proportion of all seafood in the country that is mislabeled or misidentified is between 0.5256 and 0.5944 that is 52.56% and 59.44%.

To find the difference in weights from two years ago, you will need to combine the 2 differences from the two years.
-1.56 and 0.73 becomes -1.56 + 0.73.
To add a positive and a negative number you will subtract the absolute values of the numbers AND use the sign of the number with the bigger absolute value (negative) in your answer.
|-1.56| - |0.73|
1.56 - 0.73 = 0.83
-0.83
The cat lost 0.83 (-0.83) pounds over 2 years.
Answer:
the peremiter will be 2 x one factor +2 the other factor. lets say the area of the rectangle is square feet. then the rectangle could be 8x12; so the perimeter would be 2x8+2×12 or 40 but the rectangle could also be 6 x 16 the peremiter would be 44
The answer is 25. you can find the answer by setting up a proportion.
