which z - values correspond to the bottom 30% of the standard normal distribution? round your answer to the nearest thousandth. z <

Answer

Explanation:

Step1: Use z - table

We look up the area of 0.30 in the standard normal distribution table (z - table). The z - table gives the cumulative probability from the left - hand side of the distribution.

Step2: Find the z - value

Looking up the value closest to 0.30 in the body of the standard normal table, we find that the z - value corresponding to a cumulative probability of 0.30 is approximately $z=-0.524$.

Answer:

$-0.524$
