1. A physician wanted to compare two types of pain relief. One ismedication and the other is using pressure points. To test whethermedication relieves pain faster, they have 10 migraine sufferers compareboth types of pain relief and record their observations on a standardizedscale. A coin flip was used to determine which type of headache relief eachindividual would try first. Results indicated that there was no difference inthe two types of pain relief. Complete parts (a) through (f) below.(a)What type of experimental design is this?(b)What is the response variable in this study?(c)What is the factor that is set to predetermined levels? What is thetreatment?(d)Identify the experimental units.(e)Why did the physician use a coin flip to determine which headacherelief each individual would tryfirst?(f) Draw a diagram to illustrate the design.

A cohort study of smoking and bladder cancer was conducted in a small island population. There were a total of 1000 people on the island. 400 of which were smokers and 600 were not. 50 of the smokers developed bladder cancer. 10 of the non-smokers developed bladder cancer. C. Which measure of comparison would you use to describe the absolute effect of smoking on the risk of bladder cancer among smokers? i. What is the formula for this measure of comparison? ii. Calculate this measure using the given data. iii. In one sentence, interpret the measure of comparison above.
A new cream was developed to reduce the irritation caused by poison ivy. To test the effectiveness, researchers placed an ad online asking for volunteers to participate in the study. One hundred subjects replied and were informed that one group would receive the new cream and the other group would Which of the following accurately describes the benefit of comparison in the experiment? O The overall level of irritation can be compared to see if the new cream had a significant effect. O The level of irritation for both groups can be receive a cream with no active ingredient. All 100 subjects were exposed to poison ivy. Fifty were then randomly assigned to the group with the new cream, and 50 were randomly assigned to the group with the cream with no active ingredient. After three days, the subjects' level of irritation was measured. compared to see if the new cream had a significant effect. O The level of irritation in the treatment group only can be compared to see if the new cream had…
The quality control engineer at Palmer Industries is interested in estimating the tensile strength of steel wire based on its outside diameter and the amount of molybdenum in the steel. As an experiment, she selected 25 pieces of wire, measured the outside diameters, and determined the molybdenum content. Then she measured the tensile strength of each piece. The results of the first four are recorded in the table. Tensile Strength Outside Diameter Amount of Molybdenum Place (PSI ) Y (mm) X1 (Units) X2 A 11 0.3 6 B 9 0.2 5 C 16 0.4 8 D 12 0.3 7 Using a statistical software package, the QC engineer determined the multiple regression equation to be Y’=-0.5+20X1+1X2. a) Based on the equation, what is the estimated tensile strength of a steel wire having an outside diameter of .35 mm and 6.4 units of molybdenum? b) Interpret the value of b1 in the equation.
Scientists have discovered a new bird species; however, they only found 15 birds of such species. They measured the height (in cm) of these 10 birds:12.94, 5.80, 15.47, 14.14, 7.48, 9.21, 9.79, 8.86, 17.75, 10.39. I entered the data into R as shown below: bird <- c(12.94, 5.80, 15.47, 14.14, 7.48, 9.21, 9.79, 8.86, 17.75, 10.39) Treat this data as population data. Which of the following R code computes the variance of the height of the birds? A. var(bird) B. sum((bird - mean(bird))^2)/length(bird) C. mean((bird - mean(bird))^2) D. sum((bird - mean(bird))^2)/9 E. B and C F. A and D G. B and D H. A and C
A poll was conducted on a representative sample of 600 adults living in the United States in order to investigate the decline in cable and satellite TV subscriptions. For this sample, 150 adults revealed that they are "cord cutters," (that is, they canceled their cable/satellite TV service and now only use a video streaming service). You want to estimate p, the true proportion of all US adults who are "cord cutters." Complete parts a through e. d. Give a practical interpretation of the confidence interval from part c. (Type integers or decimals rounded to three decimal places as needed. Use ascending order.) A. The probability that the true proportion of all US adults who are "cord cutters" is enter your response here lies between enter your response here and enter your response here. B.

he level of cretaine phosphokinase (CPK) in blood samples measures the amount of muscle damage for athletes. At Jock State University, the level of CPK was determined for each of 25 football players and 15 soccer players before and after practice. The two groups of athletes are trained independently. The data summary is as follows : For football players: Data for Football players n=25 Before Practice After Practice Difference (Before-After) Mean 254.73 225.6 29.13 Standard deviation 115.5 132.6 21.00 For soccer players: Data for Soccer players n=15 Before Practice After Practice Difference (Before-After) Mean 177.1 173.8 3.3 Standard deviation 60.7 64.4 6.88 Assume that all the data above are normal Test the claim that the mean CPK level has DECREASED for soccer players AFTER exercise (compared to the mean BEFORE exercise), using α=0.10. AFTER practice, do football players have a DIFFERENT mean CPK values compared to soccer players? Test this claim by…
Herbal medicine Researchers for the Herbal MedicineCouncil collected information on people’s experienceswith a new herbal remedy for colds. They went to astore that sold natural health products. There they asked100 customers whether they had taken the cold remedyand, if so, to rate its effectiveness (on a scale from 1 to 10)in curing their symptoms. The Council concluded that thisproduct was highly effective in treating the common cold.a) Identify the W’s of these data.b) Identify the variables, classify each as categorical orquantitative, and specify units if relevant.c) Are you confident about the Council’s conclusion?Explain.
r. Lyte wishes to study speed of Reaction Time to press a button in response to the onset of a lamp. The independent variable (IV) is the color of the light produced by the lamp (red, orange, yellow, green, or blue). Since only 10 participants are available, she elects to administer the IV within-subjects with all 10 participants being exposed to all five levels of the color variable. The order of the color of the light presentation is to be counterbalanced. Using concepts from the textbook, why would Dr. Lyte need to use counterbalancing in this scenario?
. Students may be classified as having a math dysfunction—and not have to take statistics—if they score below the 25th percentile on a diagnostic test. The m of the test is 75 and sX 10. Approximately what raw score is the cutoff score needed to avoid taking statistics?
What scale of measurement would be used for the following variables? Reaction Time Class size numbers on soccer players jersey
Firm handshakes seem to be related to shyness. In a sample of n = 12 people who were rated having firm handshakes, their average score on shyness was M = 43 with SS = 1170. Another sample of n = 8 people rated having weak handshakes, their average shyness score was M = 61 with SS =. 990. Use the sample data to estimate how much difference there is in shyness between people with firm vs. weak handshakes. Please do a point estimate and 90% confidence interval estimate.
