Mariana Lopes Barata and Pedro Simoes Coelho collected data from 324 music-streaming service users to identify factors that influence users to opt for paid (premium) versions of music streaming services, like spotify. They hypothesized that effort expectancy (the perceived ease with which a service can be used by a consumer) would be positively correlated with users' intentions to adopt premium versions. The researchers asked participants to rate statements such as "I find paid music streaming services easy to use." They found that, indeed, effort expectancy positively influences the intention to adopt premium streaming service versions, which suggests that_____

it may be advantageous for music streaming companies to try to influence the extent to which potential users perceive the use of the premium version as effortless.

participants who strongly agreed with the statement "I find paid music streaming services easy to use" were more likely to express loyalty to Spotify than to other streaming services.

users' intentions to pay for premium streaming services are probably unaffected by factors other than effort expectancy.

the statement "I find paid music streaming services easy to use" is not a reliable measure of effort expectancy.
