5. A clinical trial is being conducted in order to determine the efficacy of a new drug that will be used to treat rheumatoid arthritis. The efficacy of the medication will not only be determined by the physical improvement of symptoms but will also be determined by using a blood test to examine the concentration of C-reactive protein (an inflammatory marker) in an individual’s blood. If the researcher wants a margin of error for the level of C-reactive protein to be less than or equal to 2.0 mg/d and if the standard deviation for C-reactive protein concentrations among arthritis patients was previously documented at 7 mg/dL, how many patients should be recruited for each group of individuals in the study, assuming a 95% confidence interval will be used to quantify the mean differences between the control group and the treatment group?A) n for the treatment group = 95 and n for the control group = 95B) n for the treatment group = 48 and n for the control group = 48C) n for the…

Otitis media is a disease that occurs frequently in the firstfew years of life and is one of the most common reasonsfor physician visits after the routine checkup. A study wasconducted to assess the frequency of otitis media in thegeneral population in the first year of life. Table 4.15 givesthe number of infants of 2500 infants who were first seen atbirth who remained disease-free by the end of the ith monthof life, i = 0, 1, . . . , 12. (Assume no infants have been lostto follow-up.) Disease-free infants ati the end of month i0 25001 24252 23753 23004 21805 20006 18757 17008 15009 130010 125011 122512 1200 Suppose an “otitis-prone family” is defined asone in which at least three siblings of five develop otitis media in the first 6 months of life. What proportionof five-sibling families is otitis prone if we assume thedisease occurs independently for different siblings in afamily?
DiabetesA group of 10-year-old boys were first ascertained in acamp for diabetic boys. They had their weight measuredat baseline and again when they returned to camp 1 yearlater. Each time, a serum sample was obtained from whicha determination of hemoglobin A1c (HgbA1c) was made.HgbA1c (also called glycosylated hemoglobin) is routinelyused to monitor compliance with taking insulin injections.Usually, the poorer the compliance, the higher the HgbA1clevel will be. The hypothesis is that the level HgbA1c isrelated to weight. The data in Table 11.28 were obtained. **5 Compute a rank correlation between change inweight and change in HgbA1c, each over 1 year. Use this measure to directly test the hypothesis that change in weight over 1 year is related to change in HgbA1c. Report a two-tailed p-value, and provide a 95% confidence interval for the underlying rank correlation

Company determines that that the length of life of WPPX model radio is probably normal with µ=12 years and σ=2.5 year A) Lets say this radio company guarantees the radio for 9 years. What % of the radios will have to be replaced... find % of the radios that last less than 9 years? (b) Also lets say the radio company says they are going to replace the bottom 2.5% of the radios. What is thethe length of minimum guarantee period (c) What is the 90th percentile of the length of life of the radio model?
Fifty patients suffering from knee pain have volunteeredto participate in an experiment to examine the effects ofpain relief medication. Half will be assigned to take 400mg of the pain reliever every six hours, and the other halfto take 200 mg every 3 hours. The patients will reporttheir pain levels on a 1–10 scale at the beginning of theexperiment and again after 8 days on the medication.a) Define the experimental units and the response variable.b) What are the treatments? c) Describe an appropriate method to assign the volun-teers to treatments. d) An alternate design could include a control groupwho take a placebo. Describe an advantage of addinga control group.

10) Integrated circuits consist of electric channels that are etched onto silicon wafers. A certain proportion of circuits are defective because of "undercutting", which occurs when too much material is etched away so that the channels, which consist of the unetched portions of the wafers, are too narrow. A redesigned process, involving lower pressure in the etching chamber, is being investigated. The goal is to reduce the rate of undercutting to less than 5%. Out of the first 1000 circuits manufactured by the new process, only 32 show evidence of undercutting. If someone asks you the question "Can you conclude that the goal has been met?", what is the p-value that you'll report? Round the answer to four decimal places.
Promoting population growth is an important policy of an anonymous country, and an equally important issue is to improve its people's health, both physically and spiritually. In relation to this, a problem of considerable interest to the country's health officials as well as to its ordinary people is to understand the effects of smoking during pregnancy on infant health. One typical and convenient measure of infant health is birth weight since a new-born infant who is too light can put the infant at risk for contracting various illnesses. Hence a simple linear regression (SLR) model could be proposed as follows: \[ \text { weight }=\beta_{0}+\beta_{1} \text { ciga }+e, \] (1p) where weight is birth weight in ounces and ciga is average number of cigarettes the mother smoked per day during pregnancy. Using the popular ordinary least squares (OLS) method and the relevant data from BabyWeight - a dataset on some relevant variables or factors compiled from a recently-conducted random survey…
