### Frequency Distribution of Resting Heart Rates for Adults For most healthy adult women and men, resting heart rates range from 60 to 100 beats per minute. The following data represents resting heart rates of 20 adult women. Create a frequency chart with 3 classes. Round all values to 2 decimal places where possible. **Heart Rate Data:** 82, 73, 96, 65, 62, 68, 94, 81, 99, 78, 71, 69, 88, 93, 85, 61, 76, 90, 75, 61, 101 The classes are determined with a class width of 15. **Frequency Distribution Chart** | Lower Limit | Upper Limit | Lower Boundary | Upper Boundary | Midpoint | Frequency | Relative Frequency (Use decimals) | Cumulative Frequency | |-------------|-------------|----------------|----------------|----------|-----------|-----------------------------------|----------------------| | 60 | 74 | 59.5 | 74.5 | 67.50 | 10 | 0.5 | 10 | | 75 | 89 | 74.5 | 89.5 | 82.50 | 8 | 0.4 | 18 | | 90 | 104 | 89.5 | 104.5 | 97.50 | 2 | 0.1 | 20 | - **Lower Limit:** The smallest value that can sit in the class. - **Upper Limit:** The largest value that can sit in the class. - **Lower Boundary:** This is generally the lower limit of the class subtracted by 0.5. - **Upper Boundary:** This is generally the upper limit of the class added by 0.5. - **Midpoint:** The average of the upper and lower class limit. - **Frequency:** The number of times a value occurs within the class limits. - **Relative Frequency:** The proportion of the total count that occurs within the class. - **Cumulative Frequency:** The summation of the frequencies of the current class and all preceding classes. This table helps in understanding how data values are distributed over a range and frequency of occurrence, which can be beneficial in various statistical analyses.
