### Data on Weight Changes in Anorexic Women Before and After Therapy TreatmentThe table below provides the weights (in pounds) of 17 anorexic women before and after they received therapy treatment for anorexia nervosa. The weights are listed to observe the impact of the therapy on their body weight.| Before | After | Before | After ||--------|-------|--------|-------|| 89.3 | 100.3 | 89.5 | 84.2 || 89.5 | 95.0 | 93.4 | 89.6 || 79.6 | 89.0 | 95.9 | 107.3 || 83.2 | 96.8 | 96.1 | 109.5 || 96.2 | 93.3 | 81.7 | 94.8 || 81.2 | 91.9 | 83.3 | 92.3 || 98.2 | 98.1 | 97.6 | 101.5 || 83.2 | 90.6 | 101.9 | 107.6 || 101.5 | 123.0 | | |### ExplanationThis table provides a clear comparison of the weight changes in these individuals. Each pair of columns represents the weight of the same individuals before and after undergoing therapy treatment.- The first two columns show the weights of the first 9 women before and after therapy.- The next two columns show the weights of the remaining 8 women before and after therapy.### ObservationsFrom the data provided:1. Most individuals experienced an increase in their body weight after therapy.2. A few individuals showed a decrease or smaller increase in their weight post-therapy.This data helps in understanding the variations in response to therapy for anorexia nervosa among different individuals. For a more detailed analysis and possible statistical significance of these changes, one could conduct paired t-tests or similar statistical tests. ### Confidence Interval Analysis for Weight Gain after Therapy Treatment for Anorexia Nervosa**Objective:**Obtain the required confidence interval and interpret the result.**Dataset Overview:**The accompanying data provide the weights, in pounds, of 17 anorexic women before and after receiving a therapy treatment for anorexia nervosa. Your task is to find a 90% confidence interval for the weight gain that would be obtained, on average, by using the family therapy treatment.**Instructions:**1. **Access the Data:** - Click the icon provided to view the data for analysis.2. **Determine the Confidence Interval:** - Use the 'Before' and 'After' weight data to calculate the 90% confidence interval. - Formula: Confidence Interval = \( \text{mean} \pm ( z \times \frac{\text{standard deviation}}{\sqrt{n}}) \) - Here, the difference will be calculated as Before – After.3. **Calculate the Weight Difference:** - Note down the differences in weight for each of the 17 women before and after the therapy.4. **Find the 90% Confidence Interval:** - Enter your calculated confidence interval in the provided spaces [ \( \_ \_ \) , \( \_ \_ \) ] pounds. - Ensure to round this to two decimal places as needed.**Output Example:**- Insert your lower confidence limit in the left box and the upper confidence limit in the right box. ### Graphs and Diagrams:There are no graphs or diagrams associated with this content. However, detailed steps to calculate the confidence interval should be followed as specified to arrive at the accurate results.### Summary:Understanding confidence intervals and their interpretation is vital in assessing the effectiveness of treatments and interventions. Through this exercise, the calculated confidence interval will give an estimate of the average weight gain that can be expected from the therapy treatment, within a 90% certainty level.
