A researcher conducts an experiment to investigate whether reading format affects reading speed. Participants are randomly allocated to either read a passage on a digital e-reader or on a printed paper book, and their reading speed is measured. Which of the following is the null hypothesis for this study?
There will be no significant difference in reading speeds between participants who read on a digital e-reader and those who read on a printed paper book.
There will be a significant difference in reading speeds between participants who read on a digital e-reader and those who read on a printed paper book.
Participants who read on a printed paper book will have significantly faster reading speeds than those who read on a digital e-reader.
There will be a significant negative relationship between the type of reading format used and the reading speed of the participants.
