Answer:
The best conclusion is that we are 90% that the true population proportion of Republicans that voted for Mitt Romney is between 0.7273 and 0.8106.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
The 90% confidence interval for the proportion of Republican voters that had voted for Mitt Romney is (0.7273, 0.8106). The best conclusion is that we are 90% that the true population proportion of Republicans that voted for Mitt Romney is between 0.7273 and 0.8106.
First you find the total, 40, then you find how many large or blue there are, 28 then you divide by the total to be 28/40 or 7/10
( C. Rectangles and squares)
This is because a square IS a rectangle and has alike properties. A rectangle always has congruent diagonals,therefore passing the property onto the square. Even though a square is a combination of a rhombus, a rhombus doesn’t have congruent diagonals. Finally, a parallelogram can be any shape so it doesn’t necessarily have to have congruent diagonals
