ENGINEERING DATA ANALYSIS

 

 

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 reducing
current draw in a magnetic core by electronic means. They measured the current
in a magnetic winding with and without the electronics in a paired experiment. Data
for the case without electronics are provided in the following table.

a. Fit a regression line to predict current without electronics to supply voltage. Is
there 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
is the P-value?
d. Compute a 95% confidence interval for the correlation coefficient.
