Question

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)=0.7019. carry your intermediate computations to at least four decimal places. round your answer to two decimal places.

Explanation:

Step1: Use standard - normal table

Look up the value 0.7019 in the standard - normal (z - table). The z - table gives the cumulative probability $P(Z\leq z)$ for different z - values.

Step2: Find the corresponding z - value

By looking up 0.7019 in the body of the standard - normal table, we find the z - value. If the exact value is not in the table, we take the closest value.

Answer:

0.53
