If np > 5 and nq> 5 estimate p (fewer than 4) with n=13 p=0.4 by using normal distribution as an approximate to the binomial distribution if np < 5 or nq< then state that the normal approximation is not suitable.

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms
