The effect of two factors---per-chamber volume ratio (V) and injection timing(T) on the parts per million of noxious gas emitted from an engine wasstudied. The volume ratio was set at three equi-spaced levels and the time wasset at three equi-spaced levels. Two engines were built for each of the ninetreatment combinations and the amount of the gas emitted was recorded forthe 18 engines as shown in the Table.TimeVolume(T)LowMedium High7.347.87Short6.278.085.438.04Medium 6.947.488.616.517.528.32Long7.228.659.027.058.979.07a) Test the effect of volumeb) Test the effect of timec) Test the effect of the interactionPage 1 of 2304 wordsEnglish (United States)O Focus231%

A pharmacist bought a specific material from two different Providers. To compare the level of impurities present in the purchases made the two suppliers, the pharmacist measured the percentage of impurities present in each of the groups, obtaining the following: Supplier A: 1.8 2.5 1.5 1.2 1.0 Supplier B: 1.6 2.5 1.2 2.3 1.5 Which of the purchases has greater uniformity in impurities? Justify properly.

6. Setup: JP was curious about the sodium content of organic cornflakes. To investigate this, twenty 300-gram boxes of organic cornflakes were obtained and the sodium content was measured. The data (in milligrams) are as follows: 131.1, 130.7, 130.9, 129.5, 129.6, 128.8, 130.7, 128.3, 128.2, 129.7, 130.1, 129.3, 128.7, 129.0, 129.4, 130.4, 129.5, 130.1, 129.8, 130.0 Task: Perform a hypothesis test using R to determine if you can support a claim that the mean sodium content of this brand of cornflakes differs from 130 milligrams? Use a = 0.08 to make your decision. R Output: Upon running your analysis in R, you obtain the following results: One Sample t-test data: corn = 0.1121 t = -1.6659, df = alternative hypothesis: true mean is not equal to 130 19, р-value 92 percent confidence interval: 129.3458 130.0342 sample estimates: mean of x 129.69 Questions: (a) State the hypotheses used in performing this test. (b) Using the output above, state the decision (Reject or Not Reject Ho) of the…
4. Two different analytical methods were used to determine residual chlorine in sewage effluents. Both methods were used on the same samples, but each came from various locations, with differing amounts of contact time with the effluent. The concentration of Cl in mg/L was determined by the two methods, and the following results were obtained:Method A: 0.39, 0.84, 1.76, 3.35, 4.69, 7.70, 10.52, 10.92Method B: 0.36, 1.35, 2.56, 3.92, 5.35, 8.33, 10.70, 10.91What type of t test should be used to compare the two methods and why? (b) Do the two methods give different results? (c) Does the conclusion depend on whether the 90%, 95% or 99% confidence levels are used?
