**Analyzing Heights Using Statistical Methods**In this exercise, we are tasked with finding the mean and standard deviation of a set of heights. Ensure that your final answers are rounded to three decimal places.### Mean and Standard Deviation- **Mean:** [Input your answer here]- **Standard Deviation:** [Input your answer here]### Relative Frequency TableYou need to fill in the table below with the grouped relative frequencies for the specified height ranges:| Group | Frequency | Relative Frequency ||----------|-----------|---------------------|| 60 - 63.9 | | || 64 - 67.9 | | || 68 - 71.9 | | || 72 - 75.9 | | || 76 - 79.9 | | |### Histogram AnalysisA histogram is displayed above, representing the frequency of heights within different ranges. The x-axis is labeled "numbers," extending from 60 to 80, and the y-axis represents "frequency," ranging from 0 to 20.- The histogram's tallest bar is between 72 and 75.9, signifying this range has the highest frequency of height occurrences.**Discussion Point:**- **Question:** Does the data set appear to be approximately normal based on the histogram?- **Considerations:** Analyze the shape of the histogram to determine normality (bell-shaped and symmetric).(Note: This question will be hand-graded. While the computer might flag your answer as "wrong," manual review ensures you receive credit for correct insights.)This exercise encourages a comprehensive understanding of statistical analysis through real-world data interpretation. **Data Set 3**| 74.6 | 72.1 | 79.1 | 74.7 | 76.0 | 70.0 | 75.7 | 69.5 | 74.0 | 68.6 ||--------|--------|--------|--------|--------|--------|--------|--------|--------|--------|| 73.3 | 71.9 | 61.6 | 73.9 | 72.8 | 72.7 | 60.0 | 79.9 | 68.5 | 75.5 || 70.0 | 76.2 | 67.0 | 66.8 | 67.5 | 79.4 | 72.0 | 75.6 | 61.3 | 71.2 || 74.2 | 71.6 | 73.9 | 70.8 | 74.5 | 60.4 | 72.0 | 73.8 | 73.9 | 65.4 || 71.7 | 70.4 | 73.7 | 70.4 | 69.4 | 75.8 | 76.0 | 78.2 | 77.4 | 75.1 |The data set consists of a table containing numeric values arranged in a grid format with 5 rows and 10 columns. Each cell contains a floating-point number, demonstrating a potential range of observations or measurements which could represent data such as temperatures, scores, or other continuous values.
