Suppose that you are responsible for making arrangements for a business convention and that y have been charged with choosing a city for the convention that has the least expensive rooms. You have narrowed your choices to Atlanta and Houston. The table below contains samples of prices for rooms in Atlanta and Houston. Because considerable historical data on the prices of rooms in both cities are available, the population standard deviations for the prices can be assumed to be $36 in Atlanta and $31 in Houston. Atlanta Houston Atlanta Houston Atlanta Houston Atlanta Houston 75 100 80 125 95 60 80 140 60 150 75 140 125 135 115 85 65 90 60 55 125 145 75 85 80 125 65 145 120 80 100 135 100 100 95 140 60 70 120 150 120 130 115 85 80 115 80 105 80 125 75 110 135 115 60 100 65 60 85 85 80 95 55 75 150 60 105 140 85 110 70 140 90 140 70 Based on the sample data, can you conclude that the mean price of a hotel room in Atlanta is lower than one in Houston? Use a = .05 and null hypothesis is Ho : HA – µB 2 0. Enter negativ values as negative numbers. z value (to 2 decimals) p-value (to 4 decimals) We - Select your answer v that the mean price of a hotel room in Atlanta is lower than the mean price of a hotel room in Houston.
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.
