Say we decided to expand our study and asked ten more urban homeowners what they pay each month for rent. Assume the sample deviation remains the same. What will happen to our samples standard error

Complete Question

The  complete question is shown on the first uploaded image

The correct option is  C

Step-by-step explanation:

Generally the sample standard error  is mathematically represented as

Where   is the standard deviation and  n is the sample size

  Now looking at the formula we see that

So  at constant if n increases decreases

So from the question if ten more urban homeowners are asked the question the samples standard error decreases

just needed some points but try socratic
