Quizplus · Accepted Answer

Since the area to the right of z₁ is given, we need to find the z-score that corresponds to that area using a standard normal distribution table or calculator. Looking up the area 0.0869 in the table, we find the corresponding z-score to be approximately 1.36 (rounded to two decimal places). Since the z-score is positive, we know that the value of z₁ is to the right of the mean, which is 0 for a standard normal distribution. Therefore, the best choice is B, 1.36.
