In the image, we can see an assignment related to "Probabilidad y Estadística" (Probability and Statistics) from the Universidad del Valle de Santiago for a student named Ian Eli Sánchez Diaz.

The task asks the student to:

1. Solve frequency and percentage problems, with the following:
   • Descriptive reading (lectura descriptiva)
   • Bar graph (gráfica de barras)
   • Pie chart (gráfica de pastel)

The given data is a set of "Calificaciones de la materia de Estadística" (grades in the subject of Statistics):

8, 7, 10, 8, 7, 8, 5, 6, 3

It also includes a frequency table (currently empty), which needs to be filled out. The columns are:

• x: Scores
• f: Frequency
• fa: Accumulated frequency
• f%: Percentage frequency
• fa%: Accumulated percentage frequency

At the bottom of the page, there is space for descriptive analysis and the construction of bar and pie charts.

To start, I'll calculate the frequencies for the given data.

Would you like me to proceed with the frequency calculations, and then create the bar and pie charts based on this data?
