Answer :
Final answer:
To calculate the confidence intervals for u, we use the sample mean, sample size, standard deviation, and desired level of confidence. The formula for calculating the confidence interval is provided along with the corresponding Z-scores. Plugging in the values, we can calculate the confidence intervals for u.
Explanation:
To calculate the confidence intervals for u, we need to use the sample mean (T), the sample size (n), the standard deviation (o), and the desired level of confidence. The formula for calculating the confidence interval is:
- For 95% confidence interval: u ± Z * (o / √n)
- For 99% confidence interval: u ± Z * (o / √n)
Where Z is the Z-score corresponding to the desired level of confidence. For a 95% confidence interval, the Z-score is 1.96, and for a 99% confidence interval, the Z-score is 2.576. Plugging in the values, we can calculate the confidence intervals for u.
