A researcher is testing reaction times between the dominant and non-dominant
hand. They randomly start with each hand for 20 subjects and their reaction times in
milliseconds are recorded. Test to see if the reaction time is faster for the dominant hand using a
5% level of significance. The hypotheses are:
H0 : μD = 0
H1 : μD > 0
Non-Dominant Dominant
,What is the correct decision?
Accept H1
Do not reject H0
Reject H1
Reject H0
Accept H0
A physician wants to see if there was a difference in the average smokers' daily
cigarette consumption after wearing a nicotine patch. The physician set up a
study to track daily smoking consumption. In the study, the patients were given a
placebo patch that did not contain nicotine for 4 weeks, then a nicotine patch for
the following 4 weeks. Test to see if there was a difference in the average
smoker’s daily cigarette consumption using α = 0.01. The hypotheses are:
H0 : μD = 0
H1 : μD ≠ 0
, Placebo Nicotine
What is the correct decision?
Reject H0
