Final answer:
The confidence interval is (4.5, 9.5) with a 95% confidence level. We estimate with 95% confidence that the true value of the population mean is between 4.5 and 9.5.
Step-by-step explanation:
The confidence interval is (4.5, 9.5) with a 95% confidence level. This means that we estimate with 95% confidence that the true value of the population mean is between 4.5 and 9.5. The confidence interval is determined by calculating the values using the formula (sample mean - margin of error, sample mean + margin of error).
