Answer:

<u>The standard error of distribution for n = 4 is 5 and for n = 25 is 2.</u>

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

<u>Standard error for Sample₁ = 10/2 = 5</u>

Now, let's find the standard error for Sample₂

Standard error for Sample₂ = 10/√25

<u>Standard error for Sample₂ = 10/5 = 2</u>

if Base are equal power are added

like wise in first expressions power are added

but in second expressions cube of three is written as x to the power.

so they are not equal
