Question:

Traditionally, solders used in electronics assembly are made with lead. Due to numerous environmental hazards associated with lead solders (e.g., groundwater contamination and breathing in of fine lead-bearing particles), engineers are developing lead-free solders. In Soldering & Surface Mount Technology (Vol. 13, 2001), researchers compared the traditional tin–lead alloy solder to three lead-free alloys: tin–silver, tin–copper, and tin–silver–copper. A measure of plastic hardening (Nm/m2) was obtained for each solder type at each of six different temperatures. The data are given in the table.


a. Explain why the data should be analyzed using a randomized block design ANOVA.

b. Form a summary ANOVA table for the analysis.

c. Do you detect differences in the mean plastic hardening values for the four solder types? Test using α = .10.
