I have a statistics problem that I am really stumped on.

The selling price (in $) for the deluxe and standard model Ryobi wood sanders are shown for a sample of eight retail stores. Does the data suggest the difference in average selling price of these Ryobi models is more than $10 at alpha=.1

Retail Store Deluxe Standard

1 32 19

2 31 19

3 31 19

4 31 19

5 44 31

6 42 30

7 39 27

8 32 22

For the hypothesis stated abve (in terms of Deluxe-Standard)

Question 1: What is the test statistic

Question 2: What is the conclusion

Question 3: What is the p value? Fill in only one of the following statements:

If the z table is appropriate, p value =

If t table is appropriate, Pvalue is between what two values

I understand that it is t problem as sigma is unknown. I am having a problem determining degrees of freedom and test statistic
