Non-Parametric Test (Wilcoxon Rank-Sum Test or Mann-Whitney Test)Assuming a researcher designed an experiment to assess the effects of prolonged inhalation ofcadmium oxide. Fifteen laboratory animals served as experimental subjects, while 10 similaranimals served as controls (see the table below). The variable of interest was hemoglobin levelfollowing the experiment. The results are shown in the Table 3. We wish to know if we canconclude that prolonged inhalation of cadmium oxide reduces hemoglobin level.近Exposed AnimalsUnexposedAnimals (Y)14.417.414.216.213.817.116.517.514.115.016.616.015.916.915.615.014.116.315.316.815.716.713.715.314.0B3.1 Set up hypotheses for the above problemB3.2: What is the appropriate test statistic to use and why?B3.3 Report your test statistics.

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
Managers of an outdoor coffee stand in Coast City are examining the relationship between (hot) coffee sales and daily temperature, hoping to be able to predict a day's total coffee sales from the maximum temperature that day. The bivariate data values for the coffee sales (denoted by y , in dollars) and the maximum temperature (denoted by x , in degrees Fahrenheit) for each of fifteen randomly selected days during the past year are given below.

QUESTION 2 To test the effect of a new medication on pulse rate, the researcher randomly selected the 60 subjects into two groups of 30. New medicine and placebo were given to Group 1 and Group 2, respectively. Below is the Minitab output. Two-Sample T-Test and CI Group Мean StDev SE Mean 1 30 65.20 7.80 1.4 2 30 70.30 8.40 1.5 Difference = mu (1) - mu (2) Estimate for difference: 95% CI for difference: T-Test of difference = 0 (vs not =): T-Value = -2.44 -5.10 (-9.29, -0.91) P-Value=0.018 DF=57 ii) Using to.025,57 = 2.003 shows that the 95% confidence interval for the difference in mean pulse rate between new medication and placebo is (-9.29, -0.91). Hence, interpret its meaning.

Question 3 > Which of the following statements is false about the principles of a good experiment? O Studying many cases (e.g. including many patients in a study) is often more helpful than just including a few cases in the study. O Using a control group with a placebo is important since otherwise subjects in the control group may behave differently than these in the treatment group. O If we collect more information on each case (e.g. take repeated measurements on each individual) that might be helpful to obtaining more precise results in an experiment. OWe can always generalize the result of a study to the greater population so long as we randomize which patients go into which study groups. Randomizing individuals into groups is one way of preventing accidental bias from creeping into a study. Considering (controlling) more variables in planning an experiment helps ensure each study group is similar to the other study groups. > Next Question étv 18 & % %24 8. 9. 6 7 4.
2. A law school releases admissions data from past years. The median score on the LSAT for accepted students was 167. (Scores on the LSAT range from 120 to 180 points.) The first and third quartiles of LSAT scores for accepted students were 155 and 173 points, respectively. (a) Roughly sketch a histogram for what the LSAT scores for accepted students might look like based on the information given. (b) Suppose you are applying to this law school, and you read about an experiment for a new LSAT test-preparation course. Two hundred students participated. Of these, 100 were randomly chosen to take the course. They got an average score of 166 points, with an SD of 17 points. The other 100 students did not take the course and studied on their own. They got an average score of 165 points, with an SD of 18 points. Calculate the two-sample z test statistic and p-value for the null hypothesis that the course does not affect scores.
