WebThe probability mass function, P ( X = x) = f ( x), of a discrete random variable X is a function that satisfies the following properties: P ( X = x) = f ( x) > 0, if x ∈ the support S. ∑ x ∈ S f ( x) = 1. P ( X ∈ A) = ∑ x ∈ A f ( x) First item basically says that, for every element x in the support S, all of the probabilities must ... WebAug 6, 2024 · The answer is 0.0208. This one's easy; all you do is use a z-table. Look up the value in the table for z="-"2.31, then double it (since the standard normal curve is symmetrical about 0). A z-table (like the one …
WebFinding P as shown in the above diagram involves standardizing the two desired values to a z-score by subtracting the given mean and dividing by the standard deviation, as well as using a Z-table to find probabilities for … WebIn this example, that would be .00.

WebWe have taken a sample of size 50, but that value σ/√n is not the standard deviation of the sample of 50. Rather, it is the SD of the sampling distribution of the sample mean. Imagine taking a sample of size 50, calculate the sample mean, call it xbar1. Then take another sample of size 50, calculate the sample mean, call it xbar2.
