What will be an ideal response?
A sports pedagogy researcher looked at footballers’ ability to score free kicks at different distances from goal (20 yards and 30 yards). He studied a random selection of matches in which David Beckham had scored at least one free kick. Beckham scored with 21 of 81 free kicks from 20 yards, with 42 of 205 attempts from 30 yards. What can be determined from these results?
A. The p-value is less than .0001, so we can infer Beckham scores more regularly from 20 yards than 30 yards. B. The p-value is between .001 and .01, which gives strong evidence to suggest Beckham scores more regularly from 20 yards than 30 yards. C. The p-value is between .01 and .10, which gives little evidence to suggest Beckham scores more regularly from 20 yards than 30 yards. D. The p-value is greater than .10, which means there is virtually no evidence to suggest that Beckham scores more regularly from 20 yards than 30 yards.
