Answer:
0.0218
Step-by-step explanation:
The standard error SE of the sample proportion is calculated using the following equation:
Where p' is the sample proportion and n is the size of the sample.
In this case, the sample proportion p' is equal to:
Because the size of the sample is 500 adults and 304 indicated that the unemployment rate was of great concern.
Therefore, replacing p' by 0.608 and n by 500, we get:
So, the standard error of the sample proportion of adults that indicated that the unemployment rate was of great concern is equal to 0.0218
