DESIGN AND ANALYSIS OF EXPERIMENTSq4 Disk drive substrates may affect the amplitude of the signal obtained during readback.A manufacturer compares four substrates: aluminum (A), nickel-plated aluminum (B),and two types of glass (C and D). Twenty disk drives will be made, five using each ofthe substrates. It is felt that operator may have an effect on the drives, so the effectswere blocked by operator. The design and responses (in microvolts ×10-²) are givenin the following table.SubstratesABсD1843259115Analyse the data and draw conclusions.Operator37292449453∞0 w853

Trans-Generational Effects of Diet Can experiences of parents affect future children? New studies16 suggest that they can: Early life experiences of parents appear to cause permanent changes in sperm and eggs. In one study, some male rats were fed a high-fat diet with 43% of calories from fat (a typical American diet), while others were fed a normal healthy rat diet. Not surprisingly, the rats fed the high-fat diet were far more likely than the normal-diet rats to develop metabolic syndrome (characterized by such things as excess weight, excess fat, insulin resistance, and glucose intolerance.) What surprised the scientists was that the daughters of these rats were also far more likely to develop metabolic syndrome than the daughters of rats fed healthy diets. None of the daughters and none of the mothers ate a high-fat diet and the fathers did not have any contact with the daughters. The high-fat diet of the fathers appeared to cause negative effects for their daughters. What are the…
A manufacturer of a new medication on the market for Parkinson's disease makes a claim that the medication is effective in 75% of people who have the disease. One hundred fifty individuals with Parkinson's disease are given the medication, and 100 of them note the medication was effective. Does this finding provide statistical evidence at the 0.05 level that the effectiveness is less than the 75% claim the company made? Make sure to include parameter, conditions, calculations, and a conclusion in your answer.
Question 2. Lawyer Salaries [10 marks] Suppose the column Lawyer Salary in Assignment-1_S24.xlsx data file contains the salaries of articling lawyers in Ottawa firms. (a) Test at the 0.05 level of significance whether there is sufficient evidence to conclude that the average salary of articling lawyers in Ottawa exceeds $75,000. Use the critical value approach. (b) Now calculate the p-value for the result in part (a). (c) Finally calculate a 95% 1-sided confidence interval for the average salary of an articling lawyer in Ottawa. (d) Explain why the p-value and confidence interval do or do not support your conclusion in part (a). (e) Show a boxplot of the data and explain whether the assumptions of the test and confidence interval are reasonable.
A study was made of 413 children who were hospitalized as a result of motor vehicle crashes. Among 290 children who were not using seat belts, 60 were injured severely. Among 123 children using seat belts, 16 were injured severely (based on data from "Morbidity Among Pediatric Motor Vehicle Crash Victims: The Effectiveness of Seat Belts," by Osberg and Di Scala, American Journal of Public Health, Vol. 82, No. 3). For this problem we want to know, is there sufficient sample evidence to conclude, at the 0.05 significance level, that the proportion of severe injuries is higher for children not wearing seat belts? Let pi be the proportion of severe injuries among all children not wearing seatbelts and who were involved in crashes. Let p2 be the proportion of severe injuries among all children wearing seatbelts and who were involved in crashes. Which is the proper expression of Ho? Pi = P2 O Pi P2 Which is the proper expression of H1? O pi P2 Calculate p1 to 4 decimal places: Calculate p,…
