    The standard error of distribution for n = 4 is 5 and for n = 25 is 2.

    Step-by-step explanation:

    1. Let's review the information given to us for solving the question:

    Population mean = 72

    Standard deviation = 10

    Sample₁ = 4

    Sample₂ = 25

    2. For finding the standard error of the mean, we use the following formula:

    Standard error = Standard deviation / √Size of the sample

    Standard error for Sample₁ = 10/√4

    Standard error for Sample₁ = 10/2 = 5

    Now, let's find the standard error for Sample₂

    Standard error for Sample₂ = 10/√25

    Standard error for Sample₂ = 10/5 = 2
