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:

Step-by-step explanation:

Test for reaction times between the dominant and non-dominant hand.

Claim: if the reaction time is faster for the dominant hand

There are two hypotheses: the null and the alternative

The null hypothesis: Average Reaction time for proportion with dominant hand = average reaction time for proportion with non-dominant hand

Alternative hypothesis: average reaction time for proportion with dominant hand =/ average reaction time for proportion with non dominant hand
