In a study examining the effect of alcohol on reaction time, liguori and robinson (2001) found that even moderate alcohol consumption significantly slowed response time to an emergency situation in a driving simulation. in a similar study, researchers measured reaction time 30 minutes after participants consumed one 6-ounce glass of wine. again, they used a standardized driving simulation tasks for which the regular population averages μ = 400 msec. the distribution of reaction times is approximately normal with σ = 40. assume that the researchers obtained a sample mean of m = 422 for the 25 participants in the study. did alcohol consumption have an effect on reaction time? test with α = .05

Valentino starts with a population of 1,500 amoebas that increases 35% in size every hour for a number of hours, h. the expression 1,500(1+0.35)h finds the number of amoebas after h hours. which statement about this expression is true? a. it is the initial population raised to the growth factor after h hours. b. it is the sum of the initial population and the percent increase. c. it is the sum of the initial population and the growth factor after h hours. d. it is the product of the initial population and the growth factor after h hours.
