Q2) In recent seasons, Major League Baseball has been criticized for length of the games. A report pointed out that average game lasts 3 hours and 30 minutes. Sample of 17 games disclosed following times to completion. (Note that minutes have been changed to fractions of hours, so that game that lasted 2 hours and 24 minutes is reported at 2.40 hours

Sl. No.	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17
Time (x)	2.98	2.4	2.7	2.25	3.23	3.17	2.93	3.18	2.8	2.38	3.75	3.2	3.27	2.52	2.58	4.45	2.45
