- Justify is it true or false? It is possible for variables to have r=0 but still have a strong association.A data set consists of ten (x,y) pairs of numbers: (3,20)(5,13)(6,9)(8,4)(11,0)(12,0)(14,1)(17,6)(18,9)(20,16) A)Plot the data in a scatter diagram. B)Based on the plot, explain whether the relationship between x and y appears to be deterministic or to involve randomness. C)Based on the plot, explain whether the relationship between x and y appears to be linear or not linear.A varsity football player successfully scores 84% of all the field goals he kicks during in-season games. Assume each kick is independent of the others. c) Suppose that the varsity football player is unable to play for several weeks due to an injury. When he returned, he only scores 5 field goals in his next 10 kicks. Is this evidence that his success rate is now less than 84%? Explain.

Women, on the other hand, are typically employed in services which are considered more recession resistant. A sample of 165 men and a sample of 140 women were drawn. In those samples, 20 men were unemployed, and 13 of the women were unemployed. Complete parts a and b below.

- A school Psychologist is interested in the effect of violent television programs on a child's agression depending on if the show is a cartoon or not. Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child.

R matrix b. NR matrix c. Q matrix d. inverse matrix of (I –Q)B. Determine the test statistic. ____ C. 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? There is (insufficient/sufficient) evidence to warrant rejection of the claim that the direction of the kick is independent of the direction of the goalkeeper jump. The results (support/ do not support) the theory that because the kicks are so fast, goalkeepers have no time to react.
