Express the confidence interval (0.403 comma 0.487 )(0.403,0.487) in the form of ModifyingAbove p with caretpplus or minus±E. Mo difyingAbove p with caretpplus or minus±Eequals=nothingplus or minus±nothing (Type an integer or a decimal.)
1 answer:
L = 0.403 is the lower end of the confidence interval
U = 0.487 is the upper end of the confidence interval
The margin of error E is
E = (U-L)/2
E = (0.487-0.403)/2
E = 0.042
Which is half the distance from the lower to upper end
---------------------------
The midpoint of the confidence interval is the value of (read out as "p hat")
phat = (U+L)/2
phat = (0.487+0.403)/2
phat = 0.445
---------------------------
Answer : The confidence interval (0.403, 0.487) can be rewritten into the form

Answer:
L = 2m+3
Step-by-step explanation:
The area of a rectangle is found using the formula A=L*W. The area A=12m+18. The width is W=6. The length will be the expression where 6 times it gives 12m+18. The expression is 2m+3 since 6(2m+3) = 12m+18.
