### Distribution of Hours Spent Doing ChoresThe distribution of the number of hours that a random sample of people spend doing chores per week is shown in the pie chart. Use 32 as the midpoint for "30+ hours." Make a frequency distribution for the data. Then use the table to estimate the sample mean and the sample standard deviation of the data set.[Insert link to view the pie chart]#### Frequency Distribution Table| Class | Frequency, f ||-------|--------------|| 0-4 | || 5-9 | || 10-14 | || 15-19 | || 20-24 | || 25-29 | || 30+ | |#### Estimation of Statistical Measures1. **Sample Mean (x̄):** \[ \bar{x} = \text{ [Type an integer or decimal rounded to the nearest tenth as needed.]} \]2. **Sample Standard Deviation (s):** \[ s = \text{ [Type an integer or decimal rounded to the nearest tenth as needed.]} \]### Instructions for Calculations1. **Constructing the Frequency Distribution:** - Begin by filling in the frequency (f) for each class interval based on the data provided in the pie chart.2. **Estimation of Sample Mean (x̄):** - Calculate the midpoint for each class interval. - Multiply the midpoint by the frequency for each class, and then sum these products. - Divide the sum by the total number of frequencies to get the sample mean.3. **Estimation of Sample Standard Deviation (s):** - Calculate the squared difference between each midpoint and the sample mean. - Multiply these squared differences by the frequencies of each class. - Sum these values and divide by the total number of frequencies minus one. - Take the square root of the result to obtain the sample standard deviation. This exercise demonstrates how to analyze a distribution using a frequency distribution table and compute essential statistical measures. The pie chart visualization assists in understanding the distribution of time spent on chores by different individuals within a sample. ### Weekly Study Hours AnalysisThe weekly study hours of students have been analyzed and presented in a pie chart. The pie chart visually represents the distribution of study hours among different groups of students. The chart is divided into sections, each corresponding to a range of study hours and the number of students within that range. Below is a detailed description of the chart:#### Pie Chart Key- **0-4 hours**: Represented in blue (6 people)- **5-9 hours**: Represented in red (10 people)- **10-14 hours**: Represented in yellow-green (25 people)- **15-19 hours**: Represented in light green (19 people)- **20-24 hours**: Represented in turquoise (15 people)- **25-29 hours**: Represented in purple (9 people)- **30+ hours**: Represented in pink (4 people)#### Analysis- **Most Common Study Range**: The majority of students (25) fall in the 10-14 hours range.- **Least Common Study Range**: Only 4 students study for more than 30 hours a week.- **Varied Study Habits**: The data shows a wide distribution of study habits, indicating a mix of study intensities among students.### ConclusionThis analysis provides an insightful look into the study patterns of students, which can be pivotal for academic planning and resource allocation.### [Print](#) | [Done](#)---This data supports educational institutions in understanding student study patterns, which is crucial for optimizing academic support services.
