The interval contains the entire range of possible z-scores from negative infinity up to 1.24. Using the table of the standard normal distribution, we can look up the probability of obtaining a z-score less than or equal to 1.24, which is 0.8934. Then, we can subtract the probability of obtaining a z-score less than or equal to negative infinity (which is 0) from the probability of obtaining a z-score less than or equal to 1.24 to get the probability that a z-score will lie within the interval. Therefore, the answer is 0.8934 - 0 = 0.8934, rounded to four decimal places as 0.9938.
