1.In a study that assessed pulse rate at rest in different age groups, a researcher manually collected the information on 25 participants. The ages and the pulse values are presented in the below table.

• Re-arrange the data in another table while presenting mean pulse rate at rest by age categories. Every age category must include a range of 5 years only, for example: 5-9, 10-14, etc. The categories must be mutually exclusive.
• Add a third column to present the relative frequencies.
• What is the proportion of males and females in this sample?
