A researcher developed an intervention designed to increase the strength of adults 85 years or older. The researcher randomly selected 6 older adults, pretested the adults to determine their pre-intervention strength, implemented the strength training program for 10 weeks (1 training session/week), and then posttested them immediately following the last intervention session. Higher scores represent greater strength. If the researcher calculated a t-ratio of 2.62 (p=.024) and used a .05 level of significance, what conclusion should the researcher make?
