Step 1I'll solve this step-by-step:
Step 2: Recall the standard margin of error formula
For a 95% confidence level, the margin of error is always $$\pm 1.96$$ standard deviations from the mean.
Final Answer
Key Insights: - The value 1.96 comes from the standard normal distribution (z-distribution) - This is a standard statistical convention for 95% confidence intervals - The \pm indicates the interval extends both above and below the point estimate - This means 95% of the data falls within this range around the sample statistic
