Statistics i was struggling to work out if the following questions were under nomal distribution or poisson.? - works nomal nail polish to konad
- The weight of the eggs are produced by free-range poultry farm itself normally distributed with mean u and SD = 58g = 5g.
- What is the probability that a randomly selected egg weighs no more than 60 grams, as it weighs less than 55g
- What is the probability that the total weight of a sample of 12 eggs 700g atleast
- What is the probability that at leat 10 eggs weighing more than 55 grams of a sample of 12 eggs

- What is the probability that a randomly selected egg weighs no more than 60 grams, as it weighs less than 55 g:
P (x \\ \\ \\ \\ \\ \\ \\ \\ u0026lt; 60 | x> 55) = P (50 \\ \\ \\ \\ \\ \\ \\ \\ u0026lt, x \\ \\ \\ \\ \\ \\ \\ \\ u0026lt; 60) / P (x > 55) =?
- What is the probability that the total weight of a sample of 12 eggs 700g atleast
Sum of normal variables are normally distributed:
X ~ N (58 * 12.12 * 25)
P (X> 700) =?
- What is the probability that at leat 10 eggs weighing more than 55 grams of a sample of 12 eggs
(P egg weighs 55 g) = a
[12! / (10! 2 !)]*[ A 10 ^] * [(1-a) ^ 2]
