If I consume large amounts of alcohol, it is known to increase reaction time. I want to investigate the effects of small amounts of alcohol, I recorded the reaction time of 5 people before and after they drank 2 ounces of alcohol . Does the data that I provide suggest that consumption of 2 ounces of alcohol increase mean reaction time ? I assuming using 0.05 significance level to test the claim.
person 1- 6 before 7 after ( reaction time in seconds).
person 2- 8 before 8 after
person 3- 4 before 6 after
person 4 -7 before 9 after
person 5- 9 before 8 after
I want to identify the null hypothesis and alternative hypothesis.
Determine test statistic in 2 decimal places.
Determine p value in 4 decimal places.
Does the evidence support the claim of a mean reaction?
