Two hundred thirty-two of the 358 high school students surveyed at a local school say they plan on taking some form of postsecondary education. Calculate the margin of error (ME), rounded to the nearest tenth of a percent. Is it reasonable that the state education department claims the percentage for the entire state is 68%? Justify your answer.
Yes, it is reasonable because the ME is 5.0% and the population proportion of 68% falls within the sample interval of 64.8% 5.0%
No, it is not reasonable because the ME is 2.5% and the population proportion of 68% falls outside the sample interval of 64.8% 2.5%
Yes, it is reasonable because the ME is 6.3% and the population proportion of 68% falls within the sample interval of 64.8% 6.3%
No, it is not reasonable because the ME is 5.0% and the population proportion of 65% falls outside the sample interval of 73.3% 5.0%
What is the equation of the line perpendicular to 2x 5y = 35 that contains the point (10, 4)?
y=-2/5x
y=-2/5x+8
y=-5/2x+29
y=-5/2x-29
Consider the relation y = 3|x 7| + 2. Which of the followingbestdescribes the minimum or maximum point of this relation?
Minimum at (7, 2)
Maximum at (7, 2)
Minimum at (7, 2)
Maximum at (7, 2)
