# Question: 9 5 4 Ledolter and Hogg see

9 . 5 - 4 . Ledolter and Hogg (see References) note that percent yields from a certain chemical reaction for changing temperature (factor A), reaction time (factor B), and concentration (factor C) are x1 = 79.7, x2 = 74.3, x3 = 76.7, x4 = 70.0, x5 = 84.0, x6 = 81.3, x7 = 87.3, and x8 = 73.7, in standard order with a 23 design.

(a) Estimate the main effects, the three two-factor interactions, and the three-factor interaction.

(b) Construct an appropriate q–q plot to see if any of these effects seem to be significantly larger than the others.
