Note: Use Excel to perform ANOVA calculations for the following problems. You can useExcel to do other requirements as well. You need to report the relevant results only, e.g.,ANOVA table, plots, and tests conclusions. The following links for videos show how to performANOVA in Excel: Problem 1: ANOVA, Problem 2: Two-Factor ANOVA.1) It is suspected that the breaking strength of a synthetic fiber is related to the percentage ofcotton in the fiber. Five levels of cotton percentage were used, and five replicates were run inrandom order, resulting in the following data.a) Does cotton percentage affect breaking strength? Draw comparative box plots and performan analysis of variance. Use α = 0.05.b) Plot the average tensile strength against cotton percentage and interpret the results.c) Analyze the residuals and comment on model adequacy.d) If (a) results in rejecting the null hypothesis, compare the means of the treatmentsgraphically using the procedure described at class. What are your observations? Whichcotton percentages result in higher/lower average tensile strength than other treatments?Tensile StrengthCotton (%)1578 15 11 920121712 18182514181819 193019 25 2219 2335710111511

A diabetic person is interested in determining how the amount of aerobic exercise impacts his blood sugar. When blood sugar reaches 170 mg/dl, he goes out for a run at a pace of 10 minutes per mile. On different days, he runs different distances and measures his blood sugar after completing his run. The preferred blood sugar level is in the range of 80 to120 mg/dl. Levels that are too low or too high are extremely dangerous. The data generated are given in the following table: Distance (miles),x Blood sugar(mg/dl gram),y 2 136 2 146 2.5 131 2.5 125 3 120 3 116 3.5 104 3.5 95 4 85 4 94 4.5 83 4.5 75 Based on the scenario above, analyse the data with appropriate statistical methods and describe your findings in details. Use alpha=0.05 [note: use hypothesis, test statistics confidence interval etc.] ]

A recent study on driving behavior examined whether the combination of high driving skills and low safety skills is dangerous. Participants were classified as high or low in driving skill based on responses to a driver-skill inventory, then classified as high or low in safety skill based on responses to a driver-aggression scale. An overall measure of driving risk was obtained by combining several variables such as number of accidents, tickets, tendency to speed, etc. The following data were obtained. Use a 2 x 2 ANOVA with the .05 significance level to evaluate the results. What cutoff score(s) should be used? Driving Skill Low High Safety Skill Low M1=5 M2=4.5 S1=2.7 S2=3.8 N1=6 N2=6 HIgh M3=3 M4=3.5 S3=2.9 S4=2.5 N3=6 N4=6 Group of answer choices +4.35 +3.40 +3.49 +4.26

A baseball team claims that the mean length of its games is more than 1.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is not 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≠1.4." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≥1.4." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≤1.4." D. The null hypothesis expressed in words is, "the mean length of a…
