Use this information to answer the following 6 questions::

The U.S. Police department wants to know if a new campaign, to make citizens aware of the dangers of drunk driving, has been effective. They count the number of drivers who have been stopped with more alcohol in their body than the law permits for each day of the week in the week before and the week a month after the campaign starts. The results are in this data link:

Day of Week		After	Before
M		1	6
T		8	3
W		6	8
Th		2	9
F		0	6
S		2	15
Su		7	9

Assume that the number of stops of drunk drivers (before as well as after the campaign) is each normally distributed. Use the following notation:

(d): The mean of the difference in number of daily stops of drunkdrivers between those days after and those days before thecampaign.

1)Specify the null and alternative hypotheses using correct notations.

2)What is the value of the test statistic?

3)At alpha= 0.05, What is the critical value of the test?

4)At =0.05 and using the correct critical value from the preceding question

5)What is the p-value?

please show step by step, equations . dumbproof it to the best of your ability

please dont type like this P[ |X(bar)-| <25] =P[ |(X(bar)-)/(/sqrt(n))| <25>
