I am struggling with completing this. Help please?

You have conducted a double-blind experiment to determine the effects of a new drug on the reaction time of elderly drivers. You used 100 subjects in this study and randomly assigned 50 to the experimental group (received the drug) and 50 to the control group (received a placebo). You gave each of them a simulated driving test and measured their reaction time to a variety of driving hazards. You then calculated the mean reaction times for each group. next, text of significance

----Which test statistic should you use?

a. t-test for dependent or related measures

b. t-test for independent measures (i feel this is correct)

c. one-way ANOVA

d. two-way ANOVA

--- What are the degrees of freedom for the test statistic?df =50+50-2=98

----- Using a two-tailed (non-directional) test with alpha level of .05, what is the critical value of the test statistic? 1.984

------ after calculations, the calculated value is 3.68. What should youdo?

a. reject the null hypothesis (i feel this is correct)

b. fail to reject the null hypothesis

------- What is the p value in this study?
