Final answer:
To find the z-score from a standard normal distribution that satisfies the statement, we need to find the z-score that corresponds to the given percentage of observations falling below it.
Step-by-step explanation:
To find the z-score from a standard normal distribution that satisfies the statement, we need to find the z-score that corresponds to the given percentage of observations falling below it. To do this, we can use a standard normal distribution table or calculator. For example, if 15.15 percent of observations fall below a z-score, then the z-score is approximately -1.04.
