A researcher is testing the effect of a new anxiety medication on reaction time. A sample of n=16 students is obtained and each student is given the normal does of the medicine and then 30 minutes later, their reaction time is measured. The reaction times for the sample was M=220 milliseconds with SS=6000. For students in the regular population μμ=200. a.) Are these data sufficient to conclude that the medication has a significant effect on reaction time? Use a two-tailed test with αα=.05. b.)Compute r2, the percentage of variance explained by the treatment effect.
