An Environmental Engineer took a sample from the Holston River below King Port, Tennessee. The biochemical oxygen demand (BOD) test is conducted over a period of time in days. 1 2 4 6 8 10 12 14 16 18 20 Time (days) BOD (mg/litre) 0.6 0.7 1.5 1.9 2.1 2.6 2.9 3.7 3.5 3.7 3.8 She assumed that linear regression model is appropriate for the data, and she fitted a linear regression model as follows: y = 0.658 +0.178 x If you know that x is the time, and y is BOD. Find the coefficient of determination of the linear model

A biochemical engineer isolates a bacterial gene fragment and dissolves a 13.0 mg sample of the material in enough water to make 39.7 mL of solution. The osmotic pressure of the solution is 0.340 torr at 25°C. (a) What is the molar mass of the gene fragment? (b) If the solution density is 0.997 g/mL, how large is the freezing point depression for this solution (Kf of water=1.86°C/m)?

A microbe isolated from an environmental sample grows on a medium composed of agar and a mix of salts. The agar is not digested during incubation. The growth rate decreases in low CO2 conditions. The organism is likely a(n) Autotroph. Halophile. Heterotroph. Chemotroph. The answer can not be determined from the infrmation provided.

We want to study the zinc concentration from a river. We have a sample of measurements taken in 25 diﬀerent locations in a river with sample mean x = 3 and population standard deviation σ = 0.3. The population is normally distributed. 1. Find the 95% and 99% conﬁdence intervals for the mean zinc concentration in the river. 2. Is the following statement correct? “If we repeat the same experiment multiple times and each time calculate the two conﬁdence intervals...

A manufacturer of photographic flash batteries took a sample of 13 batteries from the production of any given day and used them continuously until they were used up. Battery life in hours until it ran out was: 342, 426, 317, 545, 264, 451, 749, 631, 512, 266, 492, 562 and 298. With a significance level of 0.05, there is evidence that the Battery life is more than 400 hours? (assume that life times have normal distribution)

6) I took a random sample of people from the 2000 U.S. Census and recorded the incomes. The sample size was n = 30 (with replacement). The average of the sample was $23606 and the standard deviation of the sample was $24757. Answer these questions using the statistics that I found from my sample. a) Find a 95% confidence interval for the mean income of the population. b) What assumptions must you make in order for the 95% confidence level...
