Average yield of strain A was measured as 0.905 by 20 experiments and average yield of strain B of the same organism under same experimental conditions was measured as 0.873 by 15 experiments. Standard deviation of yields of strain A was 33/1000 and standard deviation of yields of strain B was (33+15)/1000

a) Construct 95% confidence interval for the ratio of population variance of yields of strain A to population variance of yields of strain B.

b) Construct 99% confidence interval for the difference between population means of yields of strain A and strain B (μA- μB)

c) Test the null hypothesis of equality of population means of yields of strain A and strain B against the alternative hypothesis: μA > μB (use p-value approach).

3. The average yield of strain A in the bioreactor was 0.905 as a result of 20 measurements, and the average yield of strain B under the same conditions was 0.882 after 15 measurements. Standard deviations of these measurements were calculated as 0.012 for strain A and 0.015 for strain B. What assumptions are needed to build a confidence interval of 99% significance for the difference of the average yields of these two strains (uA-Ha). How can this assumption be...

The pH of 20 randomly selected lakes is measured. Their average pH is 5.7. Part C. Five of the 20 lakes have a pH less than 4.5. Part Ci. Build a 95% confidence interval for the proportion of lakes that have a pH less than 4.5. Part Cii. Test whether the population proportion of pH’s that are less than 4.5 differs from 0.5. Part Ciii. To be accurate to within 0.1 with 95% confidence, how many lakes should we measure?

The strains of prismatic beam made of extruded polycarbonate were measured using multiple strain gauges. When loaded at room temperature, normal strains are 200us and 100us, while the shear strain is 45us. The modulus of elasticity is 2.38GPa, the mass density is 1200kg/m3 , the glass transition temperature is 147°C, and the shear modulus is 0.96GPa. Determine all six independent components of the stress tensor. Clearly list all your assumptions.
