Sample Solutions Approach for Typical Problems

Let's examine a general approach to solving typical exercises found in Workshop Statistics:

Example: Calculating a Confidence Interval for a Mean

Problem: A sample of 30 students has an average test score of 78 with a standard deviation of 10. Construct a 95% confidence interval for the population mean.

Step-by-Step Solution:

1. Identify Known Values:

• Sample size, \( n = 30 \)
• Sample mean, \( \bar{x} = 78 \)
• Sample standard deviation, \( s = 10 \)
• Confidence level = 95%

2. Determine the Appropriate Distribution:

• Since the population standard deviation is unknown and \( n < 30 \), use the t-distribution.

3. Find the Critical t-value:

• Degrees of freedom, \( df = n - 1 = 29 \)
• From t-tables, \( t_{0.025,29} \approx 2.045 \)

4. Calculate Standard Error (SE):

• \( SE = \frac{s}{\sqrt{n}} = \frac{10}{\sqrt{30}} \approx 1.825 \)

5. Compute Margin of Error (ME):

• \( ME = t \times SE = 2.045 \times 1.825 \approx 3.733 \)

6. Construct the Confidence Interval:

• Lower bound: \( \bar{x} - ME = 78 - 3.733 \approx 74.27 \)
• Upper bound: \( \bar{x} + ME = 78 + 3.733 \approx 81.73 \)

Final Answer: The 95% confidence interval for the population mean score is approximately (74.27, 81.73).
