A trivia tournament organizer wanted to study the relationship between the number of points a team scores in a trivia round and the number of hours that a team practices each week. For the study, the organizer selected $55$ teams at random from all trivia teams in a certain tournament. The table displays the information for the $40$ teams in the sample that practiced for at least $3$ hours per week.

Hours practiced	Number of points per round
Hours practiced	6 to 13 points	14 or more points	Total
3 to 5 hours	$6$	$4$	$10$
More than 5 hours	$4$	$26$	$30$
Total	$10$	$30$	$40$
