c. Perform the Tukey's post hoc analysis comparing levels of copper content.No need to interpret for all levels. Does the level, which gives the lowestwarping on average in part b, providing a lower warping than other levelssignificantly? (If yes, this is the level of copper content we shouldrecommend.) 1. Analyze the data as a two way factorial design.Johnson and Leone (Statistics and ExperimentalDesign in Engineering and the Physical Sciences, Wiley,977) describe an experiment to investigate warping ofcopper plates. The two factors studied were the temperatureand the copper content of the plates. The response variablewas a measure of the amount of warping. The data were asfollows:Temperature (°C)50751001254017, 2012,916, 1221, 17Copper Content (%)608016, 2118, 1318, 2123, 2!24, 2217, 1225, 2323, 2210028, 2727, 3130, 2329, 31

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters. for a sample of 8 adults. The following table presents the results. Systolic Diastolic 126 88 104 86 103 80 110 80 122 71 117 88 130 75 118 69 Send data to Excel The least-squares regression line y=b,+b,x= 101.5438 – 0.1885x and E (x- x) = 685.5000 are known for this data. Use the critical value method to test H:B,=0 versus H : B,<0. Can you conclude that systolic blood pressure is useful in predicting diastolic blood pressure? Use the a=0.01 level of significance.

A high school teacher at a small private school assigns trigonometry practice problems to be worked on via the net. Students must use a password to access the problems, and the time of log-in and log-off is automatically recorded for the teacher. At the end of the week, the teacher examines the amount of time each student spent working on the assigned problems. The data is provided below in minutes.
