Question:
126 Organic chemistry experiment. Chemists at Kyushu University (Japan) examined the linear relationship between the maximum absorption rate y (in nanomoles)
and the Hammett substituent constant x for metacyclophane compounds ( Journal of Organic Chemistry , July 1995). The data for variants of two compounds are given in the accompanying table and saved in the ORGCHEM file.
The variants of compound 1 are labeled 1a, 1b, 1d, 1e, 1f, 1g, and 1h; the variants of compound 2 are 2a, 2b, 2c, and 2d.
a. Plot the data in a scatterplot. Use two different plotting symbols for the two compounds. What do you observe?
b. Using only the data for compound 1, fit the model E1y2 = b0 + b1x.
c. Assess the adequacy of the model you fit in part b.
Use a = .01.
d. Repeat parts b and c , using only the data for compound 2.
