#ESTADÍSTICA Hola! Tengo una duda al formar tablas para datos (discretos o enteros) agrupados: mi último intervalo termina en un (o dos) número(s) antes del valor máximo de los datos que tengo. ¿Que es más recomendable hacer?

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
