Answer:

The correct option is C

Explanation:

Generally the sample standard error is mathematically represented as

`\sigma_(\= x ) = (\sigma )/( √(n) )`

Where
`\sigma` is the standard deviation and n is the sample size

Now looking at the formula we see that

`\sigma_(\= x ) \ \ \ \alpha \ \ \ (1)/( √(n) )`

So at constant
`\sigma` if n increases
`\sigma_(\= x )` decreases

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