![**Educational Transcription: Gun Control Law Support by Gender**
**Objective:**
To compare the level of support for gun control laws between females and males using a sample of 980 individuals.
**Data Summary:**
- Total sample size: 980 people
- Female supporters: 379 out of 460
- Male supporters: 318 out of 520
**Analysis Steps:**
**a) Parameter Estimation:**
Determine the parameter for the difference in support proportions between females and males. Use proper statistical notation and provide a concise description of this parameter.
**b) Point Estimate Calculation:**
Identify the best point estimate for the difference in proportions of support between genders. Present this using the correct statistical notation and include the calculated value.
**c) Bootstrap Confidence Interval (99%):**
Calculate a 99% confidence interval using the Percentile Method. Note that a screenshot of the output from StatKey is required for this step.
- **99% CI: [______, ______]**
**d) Bootstrap Confidence Interval (95%):**
Calculate a 95% confidence interval using the Standard Error Method. Demonstrate calculations based on the bootstrap estimate of the standard error as shown in the provided graph.
- **95% CI: [______, ______]**
**e) Interpretation of the 95% Confidence Interval:**
Provide a two-part interpretation that encompasses the comparison of two parameters, ensuring clarity and statistical accuracy. Refer to lecture notes for examples of these interpretations.

The study involved analyzing data from 43,722 women aged 35 to 74 years in the US who had no history of cancer or cardiovascular disease and were not shift workers, daytime sleepers, or pregnant. The women reported their ALAN exposure at enrollment, and the data were analyzed from 2017 to 2018. ALAN exposure was categorized as 'No ALAN Exposure', and 'Any ALAN Exposure' (small nightlight, light outside the room, and light or television in the room). The presence of obesity was determined based on the measurement of general obesity, defined as having a body mass index (BMI) (calculated as weight in kilograms divided by height in meters squared) of 30.0 or higher.
