Suppose data on advertising expenditures and revenue (both in thousands of dollars) for a certain restaurant follow.

Advertising Expenditures	Revenue
1	19
2	33
4	43
6	39
10	52
14	53
20	55

(a)Letxequal advertising expenditures (in thousands of dollars) andyequal revenue (in thousands of dollars). Use the method of least squares to develop a straight line approximation of the relationship between the two variables. (Round your numerical values to two decimal places.)=

(b)Test whether revenue and advertising expenditures (both in thousands of dollars) are related at a 0.05 level of significance. (Use theFtest.)State the null and alternative hypotheses.
