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 : D = 0 H1 : D > 0 t-Test: Paired Two Sample for Means Non-Dominant Dominant Mean 63.33 56.28 Variance 218.9643158 128.7522105 Observations 20 20 Pearson Correlation 0.9067 Hypothesized Mean Difference 0 df 19 t Stat 4.7951 P(T<=t) one-tail 0.0001 t Critical one-tail 1.7291 P(T<=t) two-tail 0.0001 t Critical two-tail 2.0930 What is the correct decision? Question 2 options: Accept H1 Accept H0 Reject H0 Do not reject H0 Reject H1
