Explanation Calculation: Assume Z be the standard normal variable. Since, the area of the standard normal curve is the required probability. Then, From the given data, Z is more than − 0.75 but less than 0.5 . For the area of standard normal curve see the table 2, in appendix D. Select the number − 0.7 from the standard normal distribution table’s column and the number 0.05 from the row which is headed by z . The obtained number from the table will be 0.2266 . And, Select the number 0.5 from the standard normal distribution table’s column and the number 0.00 from the row which is headed by z . The obtained number from the table will be 0.6915 . Calculate the area. P ( − 0.75 < Z < 0.5 ) = P ( Z < 0.5 ) − P ( Z < − 0.75 ) s ( 1 ) Substitute 0.6915 for P ( Z < 0

Question

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
