Question:
There have been debates about whether older people should be allowed to drive because of their slow information processing. A researcher has developed a special program designed to enhance elder peoples information processing capabilities. This researcher randomly selects 25 women between the ages of 70 and 80 from the general population of women of this age range (whose mean reaction time is 1.8 seconds). These women take the special program. Afterwards, the women had a mean reaction time of 1.5 seconds with a standard deviation of .58. Use an alpha level of .01 and test whether the program indeed shortens reaction time.
Step 2:
On a separate sheet of paper, make sure you can identify the mean of the curve we are using for the test, the standard deviation of the curve we are using for the test, and the shape.
What is the mean of this distribution?
What is the standard error?
What is the obtained t value for this problem?
Now make sure you have the critical region and alpha marked on the curve you are using.
What is the critical value for this t-test?
