Below the number table, there is a field labeled "Provide your answer below:" where students can input their responses. Navigation buttons labeled "Previous" and "Next" are located at the bottom-right corner, indicating that this is part of a sequence in the assignment.
This kind of table might be used for statistical analysis, probability exercises, or other mathematical applications involving randomized data sets.

Transcribed Image Text:**Text from the Image:**
A researcher wants to show that the proportion of mosquitoes that carry a certain disease is greater in Region 2 than in Region 1. In a sample of 1,392 mosquitoes trapped in Region 1, 117 test positive for the disease. In a sample of 1,465 mosquitoes trapped in Region 2, 155 test positive for the disease. At the 10% level of significance, is there evidence that the proportion for Region 1 is greater than the proportion for Region 2? What is the test statistic, z, and the corresponding p-value? Compute your answer using a value from the table below.
**Table:**
The table displayed provides values to assist in hypothesis testing, likely providing p-values corresponding to different z-scores. The table is presented with rows and columns labeled with numeric values. However, specific contents of the table are not visible in detail from the image.
**Educational Explanation:**
To determine whether there is a significant difference in the proportions of mosquitoes carrying the disease between Region 1 and Region 2, the researcher will conduct a hypothesis test for proportions. The null hypothesis states that the disease proportion in Region 1 is not greater than in Region 2. A test statistic (z-score) is calculated based on the sample data, and this value is compared against a critical value from a standard normal distribution table or a p-value is calculated to draw conclusions about the hypothesis. If the computed p-value is less than the significance level (0.10), the null hypothesis is rejected, indicating a significant difference.
