Find the value of z Subscript alpha divided by 2 that corresponds to a confidence level of 89.48%.

For this case we know that the confidence level is 89.48% or 0.8948 and the significance would be: and the value of

Now we need to find a quantile in the normal standard distribution who accumulate 0.0526 of the area on each tail of the normal standard distribution and we got:

And we can use the following excel code for example:

"=NORM.INV(0.0526,0,1)"
