To construct a 95% confidence interval for the population proportion using the given information, please follow these instructions:Given:- x = 105- n = 150### Steps:1. **Calculate the Sample Proportion (p̂):** \[ p̂ = \frac{x}{n} = \frac{105}{150} \]2. **Find the Critical Value (zₐ/₂):** - Refer to the table of critical values for a 95% confidence level: - **Level of Confidence (1 - α) %:** 95% - **Area in Each Tail (α/2):** 0.025 - **Critical Value (zₐ/₂):** 1.963. **Compute the Standard Error (SE) of the Proportion:** \[ SE = \sqrt{\frac{p̂(1 - p̂)}{n}} \]4. **Calculate the Confidence Interval:** - **Lower Bound:** \( p̂ - zₐ/₂ \times SE \) - **Upper Bound:** \( p̂ + zₐ/₂ \times SE \)### Note:- Round the final answers to three decimal places as needed.### Diagram Explanation:- **Table of Critical Values:** This table provides critical values for various levels of confidence. For a 95% confidence interval, the critical value is 1.96, with an area of 0.025 in each tail of the normal distribution.Remember to substitute the calculated values into the formulas to get the specific lower and upper bounds of your confidence interval.

How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. The table shows the result of the experiment. The researchers will use a chi-square test for homogeneity to analyze the findings.

All of the conditions are met for conducting a chi- square test for homogeneity. The data came from 3 groups in a randomized experiment. All expected counts are at least 5. The 10% condition is met. The 10% condition is not needed because the eggs were not randomly selected from the population. Incorrect
