TO solve this question on "how large of a sample must Beth have to get a margin of error less than 0.04", we will use the margin of error formula:
Here, for a 80% confidence level,
(given)
Thus, margin of error, E=0.04
rearranging we get:
Plugging in gives us:
Thus, Beth's sample for the true proportion of high school students in the area who attend their home basketball games must have 256 students.
Final Price: $81
Process: 90 x 1.80 = 162
162 x 0.5 = $81

6/74 i think. So #banananutmuffin/#muffinsintotal
I did the calculation and discovered that the empire state is 441.96 meters tall, and the page is 27.94 centimeters tall. A and B don't leave you with enough room on the page, C leaves too much, D is wrong because a page doesn't have 441.96 centimeters in it, and F would also leave too much space. To check that E is the correct answer, we can divide 441.96 by 50 to get 8.83. The scale model will be short, but it yields the best results comparative to the rest. I'm so sorry if this is wrong, it just doesn't seem that there's a better answer.
