I'm having trouble solving this.

A group of 30-year-olds is interviewed to determine whether the type of music most listened to by people in their age category is independent of the geographic location of their residence. Use the chi-square test of independence, ox= 0.01, and the following contingency table to determine whether music preference is independent of geographic location. Type of Music Preferred Rock R & B Country Classical Ontario/Quebec 140 37 5 18 Geographic Alberta/Prairies 134 41 52 8 Region British 156 27 8 17 Columbia (Round your answer to 2 decimal places, e.g. 1.75.) Observed x = Type of music preferred is of region of the country
