In an article in IEEE Transactions on Instrumentation and Measurement (2001,Vol. 50, pp. 986-990), researchers reported on a study of the effects of reducingcurrent draw in a magnetic core by electronic means. They measured the current in amagnetic winding with and without the electronics in a paired experiment. Data forthe case without electronics are provided in the Table.Current Without Electronics(mA)Supply Voltage0.667.321.3212.221.9816.342.6423.663.328.063.9633.394.6234.123.2839.215.9444.216.647.48(a) Fit a regression line to predict current without electronics to supply voltage. Isthere a significant regression at a = 0.05? What is the P-value?(b) Estimate the correlation coefficient.(c) Test the hypothesis that p = 0 against the alternative p=0 with a = 0.05. What isthe P-value?

1. Analyze the data as a two way factorial design. Johnson and Leone (Statistics and Experimental Design in Engineering and the Physical Sciences, Wiley, 977) describe an experiment to investigate warping of copper plates. The two factors studied were the temperature and the copper content of the plates. The response variable was a measure of the amount of warping. The data were as follows: Temperature (°C) 50 75 100 125 40 17, 20 12,9 16, 12 21, 17 Copper Content (%) 60 80 16, 21 18, 13 18, 21 23, 2! 24, 22 17, 12 25, 23 23, 22 100 28, 27 27, 31 30, 23 29, 31

4.) A person's muscle mass is expected to decrease with age. To explore this relationship, a researcher randomly selected 10 persons from ages 40 to 79 years old and measured their muscle mass (unit). The result is as follows: X (age) Y (muscle mass) 71 64 43 67 56 73 68 56 76 65 82 91 100 68 87 73 78 80 65 84 Based on the given data, do the following: a) Plot the scatter diagram of the given data.

In the experiment, a group of college students was told that they were participating in a manual dexterity study. Half of the students were given a stack of money to count and the other half got a stack of blank pieces of paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122°F) and rate how uncomfortable it was. The following data show ratings of pain similar to the results obtained in the study. A. State null and alternative hypotheses b. Report results of statistical test, i.e., significant or not? Use .05 2-tailed alpha level. (what error might you be making) c. Report Cohen’s d value and interpret
