Answer:
99.7%
Step-by-step explanation:
Bell shaped curve by empirical rule is that if the standard deviation from the mean (left to right) is 1 deviation then about 68% of the data is in that range if it’s 2 standard deviations away then it’s 95% and 3 deviations away is 99.7%
142-100=42=3(14)
100-58=42=3(14)
Therefore the data is three standard deviations from the mean and this there is 99.7% of the data in this range.
