What type of test would best fit this problem?
An experiment was implemented to test the effectiveness of a new veterinarian product for dogs. Animals were randomly assigned to two treatments. Dogs on group treatment A received the new product and control dogs on group treatment B received a placebo. At the end of the experiment the concentrations of a certain hormone (ng/ml) was measured and the following data was obtained: DATA: Observation 1 2 3 4 5 6 Trt A 13.7 11.7 13.4 12.7 12.4 10.8 Evaluate Ho: MA UB ---against--- HA: MA # MB Trt B 13.8 14.6 12.3 13.8 10.7 1. What is the calculated "t" statistics? (round to the nearest hundredth; place the absolute value of "t" in the box below) 2. Given your "t" calculated indicate if you are going to reject or fail to reject the null hypothesis using an alpha=0.1 (reject/fail to reject; place your answer right beside the calculated "t" statistics. Do not leave a space between the two answers)
An article in Journal of Food Science (2001, Vol.66, No. 3, pp. 472-477) studied potato spoilage based on different conditions of acidified oxine (AO). which is a mixture of chlorite and chlorine diaxide. The data are shown below: AO Solution (ppm) % Spoilage 100 50 60 50 100 60 30 30 200 60 50 29 400 25 30 15 (a) Do the AO solutions differ in the spoilage percentage? Use a = 0.05. There is for significant differences in the spoilage percentage when using different AO solutions. (b) Find the P-value of the test. Estimate the variability due to random error. P-value = - (Round your answer to three decimal places.) MSE =1 - (Round your answer to the nearest integer.) (c) Plot average spoilage against AO solution and interpret the results. Which AO solution would you recommend for use in practice? v AO solution will be used. (d) Analyze the residual plots to determine model adequacy. Does the assumption of normality seem reasonable?

And we will mnake the normality assumption. (a) Suppose that we know the population variances: of = 0.1, o = 0.2. Design the test and find its pvalue. What conclusion do you reach at significance level 5%? (b) Suppose that the researchers do not trust these population vari- ance values, and would like to do the test based on the sample variances provided above. Assuming equal variance, how would your conclusions changed? %3D
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.

The authors of the paper "Statistical Methods for Assessing Agreement Between Two Methods of Clinical Measurement"† compared two different instruments for measuring a person's ability to breathe out air. (This measurement is helpful in diagnosing various lung disorders.) The two instruments considered were a Wright peak flow meter and a mini-Wright peak flow meter. Seventeen people participated in the study, and for each person air flow was measured once using the Wright meter and once using the mini-Wright meter.

cotinine levels measured in a group of nonsmokers exposed to tobacco smoke (n = 40, Mean = 60.58 ng>mL, s = 138.08 ng>mL) and a group of nonsmokers not exposed to tobacco smoke (n = 40, Mean = 16.35 ng>mL, s = 62.53 ng>mL). Cotinine is a metabolite of nicotine, meaning that when nicotine is absorbed by the body, cotinine is produced. Use a 0.05 significance level to test the claim that nonsmokers exposed to tobacco smoke have a higher mean cotinine level than nonsmokers not exposed to tobacco smoke. State null & alternative hypothesis What kind of test would this be - two tailed, left tailed or right tailed? The t test would be appropriate for testing this claim. Why is that?
