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 23**
"A fitness coach would 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 lbs, 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)."
