A student wants to know if right-handed people are more or less likely to play a musical instrument than left-handed people. The student collects data from 250 people, as shown in the two-way table. Determine whether being right-handed and playing a musical instrument are independent events using the second test for independence: If P(AnB) = P(A) *P(B), then events A and B are independent. Right-Handed Left-Handed Total Plays a Musical Instrument 44 5 50 Does Not Play a Musical 176 24 200 Instrument Total 220 30 2504.
