"A fitness coach woud like to determine whether her aerobic fitness intervention leads to a significant increase or decrease in the one rep max (i.e., heaviest possible weight that can be lifted once) for deadlifts in her group of athletes (n - 13). She finds that the mean difference = 6.5 Ibs, with a sum of squared deviation (SS) = 87.9. Calculate the t-statistic the fitness coach would observe given this data, (Be sure to round your answer to the second decimal place).

QUESTION 23 "A fitness coach woud like to determine whether her aerobic fitness intervention leads to a significant increase or decrease in the one rep max (i.e., heaviest possible weight that can be lifted once) for deadlifts in her group of athletes (n = 13). She finds that the mean difference = 6.5 Ibs, with a sum of squared deviation (SS) = 87.9. Calculate the t-statistic the fitness coach would observe given this data. (Be sure to round your answer to the second decimal place)." QUESTION 24 "A single sample t-test with a df = 27 determined that the mean of 45.75 was significantly higher after treatment. Assuming the standard error = 0.83, construct a 99% confidence interval to estimate the population mean difference." O 99% CI = 43.45 to 48.05 O 99% CI = 44,05 to 47.45 O 99% CI = 44.34 to 47.16 O 99% CI = 42.91 to 48.59 QUESTION 25 "Dr. Broadus found a significant effect of alcohol consuption on dance partner attractiveness ratings using a dependent sample t-test. If he observed a mean difference of 2.96 with a sample variance value of 21.4 after alcohol consuption, what would be the effecti size in terms of Cohen's d?" Od = 0.64 O d = 0.14 O d = -0,64 O d = 0.44
