A survey was carried out regarding the school dress code. The two-way table shows the results: Should have dress code Should not have dress code Total Middle school 30 45 High school 40 Total 55 110 Copy and complete the table

We have to Copy and complete the table The two-way table shows the results: Should have dress code Should not have dress code Total Middle school 45 - 30 = 15 30 45 High school 40 110 - 30 = 80 40 + 80 = 120 Total 55 110 165

A survey was carried out regarding the school dress code. The two-way table shows the results: Should have dress code Should not have dress code Total Middle school 30 45 High school 40 Total 55 110 Use Theorems 2 to determine whether Type of school and wanting a dress code are independent events

We have to determine whether Type of school and wanting a dress code are independent events The two-way table shows below: Should have dress code Should not have dress code Total Middle school 45 - 30 = 15 30 45 High school 40 110 - 30 = 80 40 + 80 = 120 Total 55 110 165 Use theorem: If A and B are independent events, then P A ∩ B = P A × P B From table: P A = 45 165 = 9 7 , P B = 55 165 = 11 33 and P A ∩ B = 15 165 = 1 11 P A ∩ B ≠ P A × P B So, Type of school and wanting a dress code are not independent events.
