WebbTo use this online calculator for Probable Error, enter Variable 'b' in Probable Error (b), Standard Deviation of the Sample of Size N (σn-1) & Sample Size (N) and hit the calculate button. Here is how the Probable Error calculation can be explained with given input values -> 0.109227 = 8* (1.28/sqrt (8789)). FAQ What is Probable Error? WebbFinal answer. Transcribed image text: 36% of a population has a particular characteristic. A sample of size n = 400 is taken, calculate the probability of observing a sample proportion less than 33% i.e. P (p^< 0.33) using the fact that the sampling distribution is normal and the z -score z = σp^p−p. Hint: You have already calculated σp.

Webb19 mars 2024 · We start with calculating the probability with replacement. There are four aces and 52 cards total, so the probability of drawing one ace is 4/52. If we replace this card and draw again, then the probability is again 4/52. These events are independent, so we multiply the probabilities (4/52) x (4/52) = 1/169, or approximately 0.592%.
