Question: Refer to the data in Exercise 11-15 on oxygen demand. Find a 99% confidence interval on each of the following: (a) Î² 1 (b) Î²

Refer to the data in Exercise 11-15 on oxygen demand. Find a 99% confidence interval on each of the following:

(a) Î²₁

(b) Î²₀

In Exercise

An article in the Journal of the Environmental Engi-neering Division[€œLeast Squares Estimates of BOD Param-eters€ (1980, Vol. 106, pp. 1197€“1202)] took a sample from the Holston River below Kingport, Tennessee, during August 1977. The biochemical oxygen demand (BOD) test is conducted over a period of time in days. The resulting data follow

1 2 4 6 8 10 12 14 16 18 20 Time (days): BOD (mg/liter): 0.6 0.7 1.5 1.9 2.1 2.6 2.9 3.7 3.5 3.7 3.8
