3.In a test of the ability of a certain polymer to remove toxic wastes from water,experiments were conducted at three different temperatures (low, medium,high). The data below give the percentage of the impurities that were removedby the polymer in 15 independent attempts and the incomplete rank values foreach observation.LowRankMediumRankHighRank423528141423040343244038356.529424615R, = VR2 = WR3 = 29.5i.Perform an appropriate hypothesis test at a 1% significance level.

Pork is the most preferred meat by a lot of meat consumers. Studies have shown that diets high in pork protein have favorable effects on a person's body composition. However, it is unclear whether these effects are specific to pork or whether consumption of other high protein meat diets have the same benefit. To investigate this, the nutritionist of a private diet center chose a random sample of overweight clients to participate in a 3-month program where each person is required to follow a restricted high-protein diet program with only one type of meat (chicken, fish, or pork). Before and after the program, the triglyceride level and weight of each client were recorded. Suppose the nutritionist asks your statistical advice for this study. 1. The nutritionist wants to study whether the mean change in triglyceride level of the clients differs among the three meat diets. She then asked your statistical advice considering that you have enough knowledge that using a parametric test…
We want to test the relative efficacy of a new cholesterol lowering drug A versus existing drug B. We randomize nĄ subjects with high cholesterol to take treatment A and ng subjects to take treatment B. After a l-month followup, we measure cholesterol levels in both groups. Suppose the data in the two groups are independent and YA,Y;ª,..., YA N(µA, o²) and YB,YB,.., Y,B iid N(µB,0²), where o? = 9 is known. Let Y4 and YB be the sample average cholesterol level in group A and B. 1. What is the distribution of the difference in sample means: Â =Ÿª-ŸB? Hint: what is the distribution of each group's sample average? What do we know about linear combinations of normal RVs? 2. Let A = µA - µB be the true difference in cholesterol levels in populations treated with Â-A A versus B. What is the distribution of Z = ? Vo2/na+o²/ng 3.

A study measures the absorption rate of three different types of organic chemical solvents. These solvents are used to clean industrial fabricated-metal parts and are potentially hazardous. The organic chemical solvents are Aromatics, Chloroalkanes and Esters. Aromatics ChloroalkanEsters es 0.95 1.58 0.43 1.15 0.91 0.61 0.82 0.83 0.34 1.05 1.16 0.60 0.57 0.53 1.45 Test if there is a significance difference in the mean absorption rate for the three solvents? Use a = 0.05.
An experiment was carried out to compare flow rates for four different types of nozzle. Sample sizes were 5, 6, 7, and 6, respectively, and calculations gave f= 3.68. The relevant hypothesis using alpha = 0.01 are: O a. Ho: mu1 = mu2 = mu3 = mu4 = mus Ha: At least two of the mui'S are different O b. Ho: mu1 = mu2 = mu3 = mu4 < mus Ha: At least two of the mui's are different C. Oc. Ho: mu 1 = mu2 = mu3 = mu4 = mus Ha: mu1 < mu2
