two objects and recorded whether or not the dog being tested correctly chose the object indicated. A four-year-old male beagle named Augie participated in this study. He chose the correct object 42 out of 70 times when the experimenter leaned towards the correct object. (a) (2 points) Let the parameter of interest, π, represent the probability that the long-run probability that Augie chooses correctly. Researches are interested to see if Augie understands human body cues (better than gussing). Fill in the blanks for the null and alternative hypotheses. H0 : Ha : (b) (6 points) Based on the above context, conduct a test of significance to determine the p-value to investigate if domestic dogs understand human body cues. What conclusion will you draw with significance level of 10%? (If you use an applet, please specify which applet you use, and the inputs.) (c) (5 points) Based on the above context, conduct a test of significance to determine the p-value to investigate if domestic dogs understand human body cues. What conclusion will you draw with significance level of 5%? (If you use an applet, please specify which applet you use, and the inputs.) (d) (2 points) Are your conclusions from part (b) and (c) the same? If they are different, please provide an explanation. (e) (5 points) Shown below is a dotplot from a simulation of 100 sample proportions under the assump- tion that the long-run probability that Augie chooses correct is 0.50. Based on this dotplot, would a 90% confidence interval for π contain the value 0.5? Explain your answer. (f) (4 points) Compute the standard error of the sample proportion of times that Augie chose the object correctly. 1 (g) (5 points) (h) (3 points) question? (i) (4 points) (j) (4 points) A. B. C. Construct an approximate 95% confidence interval for π using the 2SD method. What is the margin of error of the confidence interval that you found in the previous How would you interpret the confidence interval that you found in part (g)? Which of the following is a correct interpretation of the 95% confidence level? If Augie repeats this process many times, then about 95% of the intervals produced will capture the true proportion of times of choosing the correct objective. About 95% times Augie chooses the correct objective. If Augie repeats this process and constructs 20 intervals from separate independent sam- ples, we can expect about 19 of those intervals to contain the true proportion Augie chooses the correct objective. (k) (4 points) object 21 out of 35 times. Conjecture how, if at all, the center and the width of a 99% confidence interval would change with these data, compared to the original 2SD 95% confidence interval. The center of the confidence interval would . The width of the confidence interval would . (l) (4 points) Suppose that we repeated the same study with Augie, and this time he chose the correct object 17 out of 35 times, and we also change the confidence level from 95% to 99%. Conjecture how, if at all, the center and the width of a 99% confidence interval would change with these data, compared to the original 2SD 95% confidence interval. Suppose that we repeated the same study with Augie, and this time he chose the correct The center of the confidence interval would The width of the confidence interval would . .

t on a patient undergoing major abdominal operation with cardiac risk factors. Fewer patients receiving preoperative beta adrenergic blocking agents have a cardiac event than do patients receiving a placebo (5.8% vs 6.9%) with Hazard Ratio of 0.84 and a 95% CI. However, more death occurs in the patients receiving preoperative Beta adrenergic blocking agent than in those receiving a placebo (3.1% vs 2.3% with a Hazard ratio of 1.33 and a 95% CI of 1.03-1.74). According to these study results, how many patients would need to be treated with preoperative Beta adrenergic blocking agents to cause one additional death?

e based on the provided data set. You can draw the tree electronically, or draw it by hand and scan or photograph a copy—or use any other appropriate means you wish. 2. How many homoplasies are in the tree? Give the nucleotide position number(s) and tell what character states were independently derived in which species. 3. Two major clades are revealed by the tree. List the species in each clade. What can you say in general about the geographic distribution of each clade? 4. In cases where two species of Map Turtle occupy the same river system, are those species each other’s nearest relatives? Considering their phylogeny and distribution, what speciation events (including such factors as migration, vicariance, etc.) would you predict led to the species found in these rivers and their current distributions?
