On june 28, 2012 the u. s. supreme court upheld the much debated 2010 healthcare law, declaring it constitutional. a gallup poll released the day after this decision indicates that 46% of 1,012 americans agree with this decision. at a 95% confidence level, this sample has a 3% margin of error. based on this information, determine if the following statements are true or false, and explain your reasoning.

(a) we are 95% confident that between 43% and 49% of americans in this sample support the decision of the u. s. supreme court on the 2010 healthcare law.
(b) we are 95% confident that between 43% and 49% of americans support the decision of the u. s. supreme court on the 2010 healthcare law.
(c) if we considered many random samples of 1,012 americans, and we calculated the sample proportions of those who support the decision of the u. s. supreme court, 95% of those sample proportions will be between 43% and 49%.
(d) the margin of error at a 90% confidence level would be higher than 3%.

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

3750 deer

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.

elli's hot cocao is more chocolaty

here is me explaining it:

the pizza would be delivered around 5, give or take 15 minutes. this means it could be delivered anywhere from 4: 45 to 5: 15

let's say 5: 00 is equivalent to 0 on a number line and x represents time. 4: 45 would be equal to -15x because we are 15 minutes behind our starting point, 5: 00. 5: 15 would be equal to 15x because we are 15 minutes ahead of your starting point (which means you're late on the pizza delivery! )

absolute value is very confusing. the basic definition is how far you are from your starting point. if we deliver the pizza at 4: 45 (15 minutes before the starting point) we would be -15. this means we are 15 away from our starting point, 5: 00. that's the absolute value. |-15| (absolute value of negative fifteen) is equal to 15. if you did not understand this i suggest rereading this paragraph.

the normal way you would write this scenario would be 4.75 (4 and 3 quarters, or 4: 45. you can also write as a fraction.) is less than x and x is less than 5.25 (5 and 1 quarter or 5: 15). 4.75< x< 5.25 the reason why i am using numbers is because you cannot represent typical time as values on a graph, number line, or in an equation.

another way to write this scenario is with absolute value. we can write this as |x| being less than or equal to .25 (remember, this just means 15 minutes).           |x| ≤ .25.

sorry if the end was confusing. because we are talking about time this whole question is 10x harder. like i said earlier, you cannot represent time as, well, time, in a graph, equation, or number line. i set the values as follows: 1/4 or .25 for 15 minutes, and 1 for 1 hour. this is just a common way to set up graphs involving time.

|x| ≤ .25

i hope this ! : )
