A smartphone company determines that more than 60% of senior citizens in the country are still using nonsmartphones due to the complexity of operating a smartphone.

They redesign their smartphones with the simplest features that might be acceptable to senior citizens.

They randomly select n senior citizens to try their newly designed smartphone and hope for an increase of 40% of senior citizens who will use their smartphones. They calculate a power of 0.37 for that increase from a sample of 116 senior citizens. Explain to the smartphone company why they should consider a larger sample size.
