One of Varic Companys products goes through a glazing process. The company has observed glazing costs as follows over the last six weeks: Week Units Produced Total Glazing Cost

Week/ Units Produced/ Total Glazing Cost

1 9 $ 271

2 6 $ 198

3 11 $ 313

4 5 $ 196

5 7 $ 244

6 10 $ 292

Using the least-squares regression method, estimate the variable and fixed elements of the glazing cost. (Round your answers to 2 decimal places.)

Express the cost data in (1) above in the form Y = a + bX. (Round your answers to 2 decimal places.) If the company processes eight units next week, what would be the expected total glazing cost? (Round your intermediate and final answers to 2 decimal places.)
