Compute the critical value z Subscript alpha divided by 2 that corresponds to a 86​% level of confidence.
tester [92]

Answer:

z = 1.476

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.86}{2} = 0.07

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.07 = 0.93, so z = 1.476

The answer is z = 1.476
