Answer: 0.05
Step-by-step explanation:
- Sampling error is the error occurs by considering sample for study instead of entire population.
Given : The proportion of items in a population that possess a specific attribute is known to be 0.45.
Sample size : n= 100
Sample proportion of items in a population that possess a specific attribute : 
Now, the formula to find the sampling error :



Hence, the sampling error =0.05
796.300 because the 1 is less than four so it becomes a zero and the numbers in front stay the same.
