Question 34

A psychologist plans the first study comparing adults' proofreading when a passage is presented on paper and on a computer screen. No previous research has compared these two conditions.

Before collecting any data, the psychologist writes this pair of hypotheses:

Alternative hypothesis: 'Adults will identify more of the 20 spelling errors in a 600-word passage presented on paper for five minutes than in a matched 600-word passage displayed on a computer screen for five minutes.'

Null hypothesis: 'Adults will identify more of the 20 spelling errors in a 600-word passage displayed on a computer screen for five minutes than in a matched 600-word passage presented on paper for five minutes.'

Explain two problems with this pair of hypotheses.
