Vacation occupancy rates were expected to be up during March 2008 in Myrtle Beach, South Carolina (The Sun News, February 29, 2008). Data in the file Occupancy will allow you to replicate the findings presented in the newspaper. The data show units rented and not rented for a random sample of vacation properties during the first week of March 2007 and March 2008. a. Estimate the proportion of units rented during the first week of March 2007 and the first week of March 2008. b. Provide a $95 \%$ confidence interval for the difference in proportions. c. On the basis of your findings, does it appear March rental rates for 2008 will be up from those a year earlier?

Key Concepts

Hypothesis Testing

This concept involves making inferences about population parameters by comparing sample estimates to a hypothesized value. In the context of comparing proportions, hypothesis testing can determine whether the observed difference between groups is statistically significant or merely due to random sampling variability.

Confidence Intervals

Confidence intervals provide a range of values that are likely to contain the true difference between two population parameters with a specified level of confidence, such as 95%. They offer a measure of precision for the estimate and help in understanding the uncertainty associated with the sample data.

Estimation of Proportions

This concept involves using a sample to determine the ratio of occurrences (e.g., rented units) to the total number of observations. It is a fundamental idea in statistics where the sample proportion is used as an estimate of the true population proportion, which allows for further comparison and inference.

Difference in Proportions Analysis

This concept focuses on comparing two population proportions from different groups or time periods. By estimating the difference between these proportions, one can assess changes or differences in the outcomes over time or across groups, which is particularly useful in comparative studies.
