The nоrmаl distributiоn, cоmmonly known аs the bell curve due to its chаracteristic shape, is a fundamental concept in statistics. It describes how data values are distributed, with most observations clustering around the mean and fewer observations appearing as we move away from the mean. This distribution is symmetric about the mean, indicating that occurrences of values higher and lower than the mean decrease equally. One key property of the normal distribution is that probabilities correspond to areas under the curve. According to the Empirical Rule (also known as the 68-95-99.7 rule), approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. Probabilities can be calculated using z-scores, which represent how many standard deviations a value is from the mean. 1. In a statistics class, the final exam scores are normally distributed with a mean of 63 and a standard deviation of 5. What is the probability that a randomly selected student scored less than 58? {#1} 2. If the final exam scores are normally distributed with a mean of 63 and a standard deviation of 5, what score represents the 95th percentile? {#2} 3. What percentage of students scored between 58 and 68 on the final exam if the scores are normally distributed with a mean of 63 and a standard deviation of 5? {#3}
