Cardiac pacemakers contain electrical connections that are p

Cardiac pacemakers contain electrical connections that are platinum pins soldered onto a substrate. The question of interest is whether different operators produce solder joints with the same strength. Twelve substrates are randomly assigned to four operators. Each operator solders four pins on each substrate, and then these solder joints are assessed by measuring the shear strength of the pins. Completely Randomized Designs Analyze these data to determine if there is any evidence that the operators produce different mean shear strengths. (Hint: what are the experimental units?)

I just need to know what test to do in sas.

Solution

the test is F test because ther are more than 2 means , so you are going to compare 4 means
