Q5) An article in the ACI Materials Journal (Vol. 84, 1987, pp. 213–216) describes severalexperiments investigating the rodding of concrete to remove entrapped air. A 3-inch & 6-inchcylinder was used, and the number of times this rod was used is the design variable. Theresulting compressive strength of the concrete specimen is the response. The data shown isposted on BruinLearn Week 2:A. Is there any difference in compressive strength due to the rodding level? Use (α= 0.05).B. Find the P-value for the F statistic in part (a).C. Analyze the residuals from this experiment. What conclusions can you draw about theunderlying model assumptions?D. Construct a graphical display to compare the treatment means as described in your lecturenotes.

C. Analyze the residuals from this experiment. What conclusions can you draw about the underlying…

Wild irises are beautiful flowers found throughout the United States, Canada, and northern Europe. This problem concerns the length of the sepal (leaf-like part covering the flower) of different species of wild iris. Data are based on information taken from an article by R. A. Fisher in Annals of Eugenics (Vol. 7, part 2, pp. 179 -188). Measurements of sepal length in centimeters from random samples of Iris setosa (I), Iris versicolor (II), and Iris virginica (III) are as follows below.

Using all 1991 birth records in the computerized national birth certificate registry compiled by the National Center for Health Statistics (NCHS), statisticians Traci Clemons and Marcello Pagano found that the birth weights of babies in the United States are not symmetric ("Are babies normal?" The American Statistician, Nov 1999, 53:4). However, they also found that when infants born outside of the "typical" 37-43 weeks and infants born to mothers with a history of diabetes are excluded, the birth weights of the remaining infants do follow a Normal model with mean u = 3432 g and standard deviation o = 482 g. The following questions refer to infants born from 37 to 43 weeks whose mothers did not have a history of diabetes. Compute the z-score of an infant who weighs 4769 g. (Round your answer to two decimal places.) Preview Approximately what fraction of infants would you expect to have birth weights between 3100 g and 4040 g?

Twenty sculptors were asked to produce molds of a model using a different medium for each one. The options are: having the model present at the session, using a photograph and seeing the model, but having to create the sculpture from memory. The sculptor then rated the difficulty of creating each piece of artwork (1=easy; 10 = difficult). The data is provided below: Subject Model Present Photo Memory 1 9 5 5 2 3 9 6 3 6 8 9 4 1 6 10 5 5 7 7 6 9 4 1 7 8 8 10 8 6 9 4 9 8 3 8 10 1 8 10 11 8 5 10 12 8 7 5 13 6 10 3 14 9 2 7 15 5 8 9 16 1 6 8 17 7 4 7 18 10 9 1 19 3 6 10 20 10 10 10 1.
