suppose z follows the standard normal distribution. use the calculator provided, or this table, to determine the value of c so that the following is true. p(z > c)=0.8238. round your answer to two decimal places.

suppose z follows the standard normal distribution. use the calculator provided, or this table, to determine the value of c so that the following is true. p(z > c)=0.8238. round your answer to two decimal places.

Answer

Explanation:

Step1: Use the property of normal distribution

We know that $P(Z > c)=0.8238$, then $P(Z\leq c)=1 - P(Z > c)$. So $P(Z\leq c)=1 - 0.8238=0.1762$.

Step2: Look up in the standard - normal table

We look up the value $0.1762$ in the standard - normal table (the $z$ - table). The $z$ - value corresponding to a cumulative probability of $0.1762$ is approximately $-0.93$.

Answer:

$-0.93$
