Consider the statement, “Confidence intervals are underutilized” and explain what the implications might be of using or not using confidence intervals.

sorry i just need to anwers this to get points

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

umm you say your want to . but you do know that this is the mathematics.
