It would be smaller.

Step-by-step explanation:

Given that :

The number of the strawberries that are unfit for sell, x = 24

The total number of the strawberries to inspect, n = 156

Total number of the strawberries to be picked = 1000 strawberries

Therefore,

$\widehat p =\frac{x}{n}$

$=\frac{24}{156}$

= 0.1538

$\widehat p =\frac{x}{n}$

$=\frac{24}{1000}$

= 0.024

Therefore, the standard deviation of the sample proportion would be smaller.
