because all normal distributions are the same when we standardize, we can find the areas under any normal curve from a single table or using our calculator. standard normal probability table: this is a table of areas under the standard normal curve. the table entry for each value z is the area under the curve to the left of z. table entry for z is the area under the standard normal curve to the left of z. 1) what percent of data is below a z - score of 0.54?

Answer

Explanation:

Step1: Use standard - normal table

Look up the z - score of 0.54 in the standard normal probability table. The table gives the area (proportion) of data to the left of the z - score.

Step2: Find the proportion

From the standard normal table, the area to the left of z = 0.54 is 0.7054.

Step3: Convert to percentage

To convert the proportion to a percentage, multiply by 100. So, 0.7054×100 = 70.54%.

Answer:

70.54%
