Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel). Hotel occupancy data for February in two consecutive years are as follows. Current Year Previous Year Occupied Rooms 1,470 1,458 Total Rooms 1,750 1,800 current 0.84 previous 0.81 test statistic 2.35 p-value 0.0087 (d) What is the 95% confidence interval estimate of the change in occupancy for the one-year period? (Round your answers to four decimal places.) to Do you think area officials would be pleased with the results? The 95% confidence interval ---Select--- is completely above or contains or is completely below zero. This suggests that the occupancy rates for the current year are ---Select--- higher or lower than the occupancy rates for the previous year, therefore the officials would ---Select--- not be or be pleased with the results.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
