- The maximum weights (in kilograms) for which one repetition of a half squat can be performed and the jump heights (in centimeters) for 12 international soccer players are shown in the attached data table with a sample correlation coefficient r of 0.771. Remove the data entry for the international soccer player with a maximum weight of 180 kilograms and a jump height of 64 centimeters. Describe how this affects the correlation coefficient r.Suppose that you want to do statistical significance tests for four correlations and you want your EWa to be .05. What PCa would you use if you apply the Bonferroni procedure?1. Calculate the correlation coefficient. 2. What do these data indicate about the height of the initial drop of a roller coaster and the duration of the ride? O A. Generally, rides on coasters with a greater initial drop tend to last somewhat shorter, because the correlation indicates a moderate association.O B. Generally, rides on coasters with a greater initial drop tend to last longer, because the correlation indicates a strong association.O C. Generally, rides on qpasters with a greater initial drop tend to last somewhat longer, because the correlation indicates a moderate association.O D. Generally, rides on coasters with a greater initial drop tend to last somewhat longer, because the correlation indicates a weak association.
- Suppose that you want to do statistical significance tests for four correlations and you want your to be .05. What would you use if you apply the Bonferroni procedure?9) determine the critical values of the (r)and use your finding to state whether or not the given (r) represents a significant linear correlation. significance level = .05 r = .398 ñ = 17
