Verify whether n is large enough to use the normal approximation by checking the two appropriate conditions.. For the above coin-flipping question, the conditions are met because n ∗ p = 100 ∗ 0.50 = 50, and n ∗ (1 – p) = 100 ∗ (1 – 0.50) = 50, both of which are at least 10.So go ahead with the normal approximation. Show Instructions. The binomial probability, in this case, is 0.432. The final exam scores in a statistics class were normally distributed with a mean of $58$ and a standard deviation of $4$. It is defined by two parameters mean ('average' m) and standard deviation (σ). The distribution is symmetrical regarding the average. representation of the area you want to find. If we assume that the distribution of the return is normal, then let us interpret for the weight of the students in the class.
