Suppose we want to know the effect on driving of a drug for cold and allergy, in a study in which the same people were tested twice, once after 1 hour of taking the drug and once when no drug is taken. Suppose we obtain the following data, which represent the number of cones (placed in a certain pattern) knocked down by each of the nine individuals before taking the drug and after an hour of taking the drug.

No drug	0	0	3	2	0	0	3	3	1
After drug	1	5	6	5	5	5	6	1	6

Assuming that the difference of each pair is coming from an approximately normal distribu- tion, test if there is any difference in the individuals' driving ability under the two conditions. Use α = 0.05.
