**Survey on Job Satisfaction**A survey was conducted at a company to assess how satisfied employees are with their jobs. The survey used a scale from 1 to 3, with 1 indicating "very satisfied" and 3 indicating "very dissatisfied." Out of the numerous employees, a sample of 50 individuals participated in the survey.### Visualization Overview#### Histogram of Job Satisfaction- The histogram displays the distribution of satisfaction levels among participants.- X-axis: Satisfaction Levels (1, 2, 3)- Y-axis: Number of Respondents - Level 1: 18 responses (36%) - Level 2: 19 responses (38%) - Level 3: 13 responses (26%)The bar heights visually represent the number of respondents for each satisfaction level, showing that Level 2 had the highest count.#### Frequencies Table- **Level 1**: Count = 18, Probability = 0.3600- **Level 2**: Count = 19, Probability = 0.3800- **Level 3**: Count = 13, Probability = 0.2600- Total participants = 50- All levels were reported, with no missing responses.### Confidence IntervalsConfidence intervals for satisfaction levels were computed using score confidence intervals:#### 90% Confidence Intervals- **Level 1**: Lower CI = 0.258197, Upper CI = 0.476177- **Level 2**: Lower CI = 0.276014, Upper CI = 0.496306- **Level 3**: Lower CI = 0.172179, Upper CI = 0.372461- Calculated with an alpha (α) of 0.900#### 95% Confidence Intervals- **Level 1**: Lower CI = 0.211239, Upper CI = 0.54151- **Level 2**: Lower CI = 0.227329, Upper CI = 0.560788- **Level 3**: Lower CI = 0.135733, Upper CI = 0.44086- Calculated with an alpha (α) of 0.950#### 85% Confidence Intervals- **Level 1**: Lower CI = 0.269595, Upper CI = 0. **Section (a):**- **Task**: Determine the proportion of employees who chose the satisfaction rating 2 (neutral). - **Find the 99% Confidence Interval**: Calculate the 99% confidence interval of the population proportion associated with the satisfaction rating of 2. Round your answers to three decimal places. Enter your answer: \[ (\_\_\_\_\_\_, \_\_\_\_\_\_) \]**Section (b):**- **Interest of the Company**: The company wants to know which confidence intervals associated with the satisfaction rating of 1 (very satisfied) contain the proportion 0.25, or 25%. Determine which confidence levels satisfy this. (Select all that apply.) - [ ] 85% - [ ] 90% - [ ] 95% - [ ] 99%- **True or False Statement**: Determine if the following statement is true or false: "If the same sampling type was done numerous times and a 90% confidence interval was given each time, at least 90% of these intervals would contain the true population proportion of people selecting 1 as the satisfaction rating." - ( ) True - ( ) False
