A psychologist is planning an experiment in which pupils will have either 30 seconds or 90 seconds to learn the same list of 15 invented words. Each pupil will then have two minutes to write down as many words as they can remember.
An earlier study reported the following findings:
| Learning time | Mean number of invented words correctly recalled out of 15 |
|---|---|
| 30 seconds | 5.2 |
| 90 seconds | 8.7 |
Using the findings from the earlier study, state an operationalised alternative hypothesis for the psychologist's experiment.
