Answer:
86.6% ; 93.4%
Step-by-step explanation:
To obtain the population proportion from the sample, we calculate the confidence interval ;
Confidence interval = phat ± margin of error
Phat = 90% ; margin of error = +3.4%
Hence,
90% ± 3.4%
(90 - 3.4)% ; (90 + 3.4)%
86.6% ; 93.4%
Hey there!
Usually when people are trying to find absolute value we are trying to REMOVE your NEGATIVE in FRONT of your given number and make them almost positive (e.g. 0)
|20| = (positive) 20 because it’s the absolute value of itself ; if your equation was |-20| you would have to say your absolute value would be 20
Answer: |20| = 20 ☑️
Good luck on your assignment and enjoy your day!
