Suppose, a sales man spends 10 minutes on an average wit
customer. Here the random variable X refers to the amount of tim
spend by him with a randomly selected customers. In that situatio.
find the probability that:
(i) he will spend more than 12 minutes,
(ii) he will spend between 8 to 14 minutes,
(iii) he will not spend more than 11 minutes.
(II) Let, X follows the normal distribution with mean 15 and standard
deviation is 3. Then find, P(0 < X < 15).
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.
