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:
Occupied Rooms	= 1,440	
Total Rooms	= 1,800

Previous year :
Occupied Rooms = 1,463	
Total rooms = 1,900. Conduct a hypothesis test, what is the p value to 4 decimals 

We are conducting a hypothesis test to determine whether there is a significant difference in the hotel occupancy rates between the current year and the previous year.

The hotel occupancy rate can be calculated as:

\[
\text{Occupancy Rate} = \frac{\text{Occupied Rooms}}{\text{Total Rooms}}
\]

The sample proportions for the current and previous years are:

\[
\hat{p}_1 = \frac{1440}{1800} = 0.8
\]
\[
\hat{p}_2 = \frac{1463}{1900} = 0.769
\]

### Step 1: Hypotheses
- **Null Hypothesis (\(H_0\))**: There is no difference in occupancy rates between the current and previous year. \(\hat{p}_1 = \hat{p}_2\)
- **Alternative Hypothesis (\(H_a\))**: There is a difference in occupancy rates between the two years. \(\hat{p}_1 \neq \hat{p}_2\)

### Step 2: Calculate the test statistic
We can use a two-proportion z-test for this hypothesis test.

The pooled proportion is given by:

\[
\hat{p} = \frac{\text{Occupied Rooms in both years}}{\text{Total Rooms in both years}} = \frac{1440 + 1463}{1800 + 1900}
\]

The standard error (SE) for the difference in proportions is calculated as:

\[
SE = \sqrt{\hat{p}(1-\hat{p}) \left(\frac{1}{n_1} + \frac{1}{n_2}\right)}
\]

The test statistic (z-value) is:

\[
z = \frac{\hat{p}_1 - \hat{p}_2}{SE}
\]

### Step 3: Calculate p-value
We will calculate this and find the p-value using a two-tailed test. Let me compute these values.The p-value for this hypothesis test is approximately 0.0265. 

Since this p-value is less than the common significance level of 0.05, we can reject the null hypothesis, meaning there is a statistically significant difference in the hotel occupancy rates between the current and previous year.

1. How is a two-proportion z-test used in other contexts?
2. What is the effect size and how could it be calculated in this scenario?
3. What other factors might influence hotel occupancy besides the year difference?
4. How do confidence intervals for proportions compare to hypothesis testing?
5. What assumptions are made in the z-test for proportions?

**Tip:** In hypothesis testing, the p-value helps you determine whether the observed data significantly deviates from the null hypothesis, but always consider the context and possible real-world implications before drawing conclusions.
