Answer:
(0.4958, 0.7422)
Step-by-step explanation:
Let p be the true proportion of water specimens that contain detectable levels of lead. The point estimate for p is . The estimated standard deviation is given by . Because we have a large sample, the 90% confidence interval for p is given by where is the value that satisfies that above this and under the standard normal density there is an area of 0.05. So, the confidence interval is , i.e., (0.4958, 0.7422).

Answer:
To find out how much trim you would need for the window, you would need to calculate the Circumference.
Step-by-step explanation:
<u>Circumference</u> is the length around a circle and is calculated using the following formula.
In which C is the circumference and r is the radius. Since we already know the radius all we have to do is plug it into the equation and solve for C.
<u>Answer:</u> The window has a Circumference of 26.389 feet so you would need that amount of trim to fit the area around the window.
