3. Sports psychologists believe that athletes who have higher mental toughness tend to perform better in competition. To these this claim, they obtain a random sample of 20 competitive runners. Of these 20, 10 are randomly selected to complete mental toughness training while the other 10 do not receive this training. After 2 weeks, psychologists measure the length of time it takes all 20 participants to complete a 5-kilometer race in a competitive event. The race times are listed below, in minutes: Training 14 12 16 14 15 13 17 16 21 18 No training 2223 20 26 25 22 28 21 22 24 22 o these data support the psychologists' prediction by monstrating that runners with mental toughness training mplete the race faster, on average, than runners who did not ceive the training (alpha < .01)?

![3. Sports psychologists believe that athletes who have higher
mental toughness tend to perform better in competition. To
these this claim, they obtain a random sample of 20
competitive runners. Of these 20, 10 are randomly selected
to complete mental toughness training while the other 10
do not receive this training. After 2 weeks, psychologists
measure the length of time it takes all 20 participants to
complete a 5-kilometer race in a competitive event. The
