find the z - score such that the area under the standard normal curve to the left is 0.42.\n\n□ is the z - score such that the area under the curve to the left is 0.42.\n(round to two decimal places as needed.)

find the z - score such that the area under the standard normal curve to the left is 0.42.\n\n□ is the z - score such that the area under the curve to the left is 0.42.\n(round to two decimal places as needed.)

Answer

Explanation:

Step1: Use z - table

We use the standard normal distribution table (z - table). The z - table gives the cumulative probability (area to the left) for a given z - score.

Step2: Look up the value

We look for the value closest to 0.42 in the body of the z - table. The closest value in the standard normal table to 0.42 gives us the z - score. From the z - table, the z - score corresponding to an area of 0.42 to the left is approximately - 0.20.

Answer:

  • 0.20
