Suggest the average available for all hotel rooms. Determine the point estimate of the average number of available hotel rooms in this lesson from each sample. Make and Interpret a 95% confidence level for the true mean number of available hotel rooms, based upon the point estimate of each sample. Discuss how the confidence intervals will change depending upon whether the population standard deviation is known or unknown.
