A reseаrcher develоped аn interventiоn designed tо increаse the grip strength of adults 85 years or older.  The researcher randomly selected 16 older adults and used available body mass index (BMI) data, to create 8 matched pairs on BMI. Within each pair, the researcher randomly assigned 1 participant to the intervention and 1 to the control group. The strength training program was implemented for 10 weeks (1 training session/week).  Immediately following the intervention, all adults were tested for grip strength.  Higher scores represent greater grip strength. What effect will increasing the number of matched pairs (instead of 8 pairs having 80 pairs) have on statistical power?
