305 divided by 5 equals 61.

If you have questions, ask please :)

A sample of n = 4 scores has SS = 48. What is the estimated standard error for this sample? Group of answer choices
mylen [45]

Answer:

2

Step-by-step explanation:

We have

n = 4 scores

SS = 48

For this question, we are required to find the estimated standard error

To get this, we first solve for the variance

S² = SS/n-1

= 48/4-1

= 48/3

= 16

Then S² = 16

S = √16

S = 4

Then the estimated standard error is given by:

S/√n

= 4/√4

= 4/2

= 2.

The estimated standard error is 2.
