Question 10

It is known that the average time an adult can read a 1000-word passage is 4.5 minutes. A psychologist is interested in whether exercising eye muscles would make this process faster. 25 adults voluntarily participate in the research, and they do eye exercises for 5 minutes every day for 2 weeks. After the training session, they come to the researcher's lab and read a 1000-word passage while being timed. The dataset is provided in the Excel file.

Based on the information above, which of the following would be a well-formed alternative hypothesis for this research study?

  • A. Participants will read slower or faster after the 2-week training session compared to the adults in general.
  • B. Participants will read at the same pace after the 2-week training session as the adults in general.
  • C. Participants will read faster after the 2-week training session compared to the adults in general.
  • D. Participants will read at a different pace after the 2-week training session compared to the adults in general.
  • E. Participants will not read faster after the 2-week training session compared to the adults in general.
