The proportion of items in a population that possess a specific attribute is known to be 0.45. a. If a simple random sample of s
ize nequals100 is selected and the proportion of items in the sample that contain the attribute of interest is 0.48, what is the sampling error?
1 answer:
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
