Answer:
± 4.05
Explanation:
Data provided in the question:
Random sample size = 15
Standard deviation = 8
Confidence level = 95%
Now,
Margin of error is given as:
Margin of error = ± [ ( z × s ) ÷ √n ]
Here,
From standard z table for 95% confidence level z = 1.96
Margin of error = ± [ ( 1.96 × 8 ) ÷ √15 ]
or
Margin of error = ± [ 15.68 ÷ 3.873 ]
or
Margin of error = ± 4.05
