O (a) Determine the 95% confidence interval for the population mean. (Round your answers to two decimal places.) (b) Select which correctly describe the 95% confidence interval. (Select all that apply.) O We are 95% confident that the mean height of the entire business is larger than this interval. We are 95% confident that the mean height of the entire business is in this interval. 95% of employees have heights in this interval. 95 employees have heights in this interval. The 95% confidence interval is a subset of the 85% confidence interval. The upper height represents the 95th percentile. The 85% confidence interval is a subset of the 95% confidence interval. We are 5% confident that the mean height of the entire business is in this interval.
