Construct the lower bound of a confidence interval using the following information: n = 95; mean = 49.379; standard deviation = 26.933; alpha = 0.01. Remember that alpha = 0.05 is for a 95% confidence interval and alpha = 0.01 is for a 99% confidence interval. 7.706 42.25 59.365 10.489

Construct the lower bound of a confidence interval using the following information: n = 29; mean = 46.069; standard deviation = 31.574; alpha = 0.05. Remember that alpha = 0.05 is for a 95% confidence interval and alpha = 0.01 is for a 99% confidence interval. 53.185 99.226 34.061 3.822
We provide a sample mean, sample size, population standard deviation, and confidence level. In each case, use the one-mean z-interval procedure to find a confidence interval for the mean of the population from which the sample was drawn. $$\bar{x}=20, n=36, \sigma=3, \text { confidence level }=95 \%$$
