Given

Confidence level = 85%

Find

Critical Value

Step-by-step explanation

As we know that the critical value of a distribution is the value beyond which the rejection region lies.

for a confidence interval the rejection region lies beyond two values , the positive and negative critical value.

so,

$\pm z_{(\alpha)/(2)=}\operatorname{\pm}z_{(0.15)/(2)=\pm1.439}$

Final Answer

The critical value is

$\pm1.439$

round off to two decimal places =

$\pm1.44$
