Using the z-distribution, it is found that the margin of error is of 0.059.
We are given the standard deviation for the population, hence the <em>z-distribution</em> is used.
<h3>What is the margin of error for a z-confidence interval?</h3>It is given by:
In which:
- z is the critical value.
is the population standard deviation.
- n is the sample size.
In this problem, the parameters are:
.
- Confidence level of 0.90, hence, using a z-distribution calculator, the critical value is z = 1.645.
Then:
The margin of error is of 0.059.

Answer:
y = 1/2
Step-by-step explanation:
A matrix multiplied by its inverse gives the identity matrix;
Based upon knowing this:
6(-1) + 14y = 1
14y = 7
y = 1/2
