This problem has been solved! see the answerpull-strength tests on 10 soldered leads for a semi conductor device yield the following results in pounds force required to rupture the bond: 19.9 12.7 13.2 16.9 10.618.8 11.1 14.3 17.0 12.5another set of 8 leads was tested after encapsulation to determine whether the pull strength has beenincreased by encapsulation of the device, with the following results24.9 22.8 23.6 22.1 20.4 21.6 21.8 22.5comment on the evidence available concerning equality of the two population variances.
