Construct a 95% confidence interval about null if the sample size n is 34 lower bound
Upper bound
The 95% confidence interval about null is (-∞, ∞).
To construct a 95% confidence interval, we need to know the mean and standard deviation of the sample data. With only the sample size provided (n = 34), we don't have enough information to proceed with the calculation.
To construct a confidence interval, you usually need the following information:
1. Sample mean (x̄)
2. Sample standard deviation (s)
3. Sample size (n)
4. Confidence level (typically expressed as a percentage, such as 95%)
Without having the sample mean and standard deviation, we can't provide the lower bound and upper bound values for the confidence interval.
To construct a 95% confidence interval, we need to know the mean and standard deviation of the population.
Since the question states "about null," it suggests that we are working with a hypothesis test or analyzing a sample distribution.
Without more information or a specific null hypothesis, it is not possible to provide an accurate answer. Can you please provide more details or clarify the question?
