Question
please answer in text form and in proper format answer with must explanation , calculation for each part and steps clearly

Transcribed Image Text:In soccer, serious fouls result in a penalty kick with one kicker and one defending goalkeeper. The accompanying table summarizes results from 303 kicks during games among top teams. In the table, jump direction indicates which way
the goalkeeper jumped, where the kick direction is from the perspective of the goalkeeper. Use a 0.05 significance level to test the claim that the direction of the kick is independent of the direction of the goalkeeper jump. Do the results
support the theory that because the kicks are so fast, goalkeepers have no time to react, so the directions of their jumps are independent of the directions of the kicks?

OA. Ho: Jump direction is dependent on kick direction.
H₁: Jump direction is independent of kick direction.
OB. Ho: Jump direction is independent of kick direction.
H₁: Jump direction is dependent on kick direction.
OC. Ho: Goalkeepers jump in the direction of the kick.
H₁: Goalkeepers do not jump in the direction of the kick.
OD. Ho: Goalkeepers do not jump in the direction of the kick.
H₁: Goalkeepers jump in the direction of the kick.
