A sample of 14 participants took part in a hearing experiment. Among other things, the absolute hearing threshold (in decibels) was measured for eachparticipant. The 14 measurements were as follows:25, 22, 18, 35, 21, 21, 21, 18, 18, 39, 39, 36, 36, 33Send data to calculatorDraw the frequency polygon for these data using an initial class boundary of 17.5, an ending class boundary of 45.5 and 4 classes of equal width.

Based on the information on the image answer the following Question: 1- Organize the student's weights in a frequency table of 6 classes with suitable class width (class interval). (You have to construct a table with classes, frequency, cumulative frequency, relative frequency, and percent relative frequency).
Resting Pulse: earlier this semester we determined our resting pulse. Seventy-nine individuals participated in this data collection. The mean heart rate for all individuals was 65.34 beats per minute. A random sample of 30 heart rates having a mean of 64.97 beats per minute is presented here. Build a frequency table of these data containing six (6) classes with the lower llimit of the second class at 54 beats per minute. Build a chart appropriate for the presentation of these data.

I'm not sure where is my mistake solving this problem. I have revised my calculation three times already and I'm not sure if the step to solve it is wrong or if it is my rounding the problem. Thank you for your help
The upper class boundary of one of the classes in a frequency distribution table is 135.5, and each class on the same table has a width of 25. What is the lower class limit of the said class? What is the class mark of the same class?
