If the weight of the students expressed by ?“a random variable” with a distribution of N(μ, σ), find: ?(? − ( ? 3 )? ≤ ? ≤ ? + ( ? 3 ) ?). 2. It assumed that the maximum temperature in Oman is normally distributed with a mean of D and a standard deviation of D/2 for which: ?(? − ? ≤ ? ≤ ? + ?) = 0.5934. calculate the value of “ ? “
