Use this worksheet to study the effect of sample size on the shape of the sampling distribution with µ = 24 and sigma = 2. Purple shaded area represents P(x_a ≤ X ≤ x_b). As you adjust the sample size n, note how the standard error of the mean changes, and thus how the shape of the sampling distribution changes. Adjust points x_a and x_b on the x-axis to compute probabilities.
