Answer:
The margin of error for the proportion of students at OSU who have ever used an online dating app in 99% confidence level is 10.8%
Step-by-step explanation:
margin of error (ME) around the mean can be found using the formula
ME= where
- z is the corresponding statistic in the given confidence level (2.58)
- p the proportion of students at OSU who have ever used an online dating app in the random sample. (0.43)
- N is the sample size (140)
Putting the numbers in the formula we get
ME= ≈ 0,10795 ≈ 10.8%
Then the confidence interval for the proportion of students at OSU who have ever used an online dating app in 99% confidence level would be 43%±10.8%
Answer:
C. 4/3x - 5
Step-by-step explanation:
First, to eliminate unnecessary answers, we can find out how to make sure the line will be perpendicular to -3/4. You will know if two lines are perpendicular if the slopes are COMPLETELY opposite. For example, 4/3 is COMPLETELY opposite from -3/4.
-3/4......4/3
So, now we know we eliminated two answers. We are left with A and C.
Then, I opened an online graphing calculator and found out which one of these lines pass through (12,9). Attached is a picture proving that answer C's line crosses through this point. Please mark me Brainliest; I need it to move on in my account! =D
