A mаrket reseаrcher studied three bаckgrоund music cоnditiоns in a supermarket: French accordion music, Italian string music, and no music. Under each condition, the researcher recorded how many bottles of French, Italian, and other wine were purchased. The table below summarizes the observed frequencies. The researcher wants to use the Chi-Square test to determine whether there is a relationship between background music and type of wine purchased. What is the expected frequency for the number of bottles of French wine purchased when Italian music was playing?
