Most sports injuries are immediate and obvious, like a broken leg. however, some can be more subtle, like the neurological damage that may occur when soccer players repeatedly head a soccer ball. to examine long-term effects of repeated heading, downs and abwender (2002) examined two different age groups of soccer players and swimmers. the dependent variable was performance on a conceptual thinking task. following are hypothetical data, similar to the research results.

a. use a two-factor anova with = .05 to evaluate the main effects and interaction.
b. calculate the effects size (n2) for the main effects and the interaction.
c. briefly describe the outcome of the study
factor b: age
college older
soccer n= 20 n=20
factor a: m=9 m= 4
sport t= 180 t = 80
ss= 380 ss= 390

swimming n= 20 n = 20
m = 9 m = 8
t = 180 t =160
ss = 350 ss= 400

ex2 = 6360

answer: it's d

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
