Answer:
I know for a fact that x is 4.3 so that means 4.2 is less than x and 4.4 is greater than x
here are the steps whether you like it or not
step:1 4.1^2+1.3^2=18.5
step:2 √18.5=4.3
Just replace x with whatever , and see if it works. If it works then it is a solution; otherwise it's not.
1^2 is not 2
(1/2)^2 isn't 2 either...
and so on
Answer:
No; the absolute value of a negative number is equal to its opposite
Step-by-step explanation:
Answer:
The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).
