The specification for the pull strength of a wire that connects an integrated circuit to its frame is 10 g or more. Units made with aluminum wire have a defect rate of 10%. A redesigned manufacturing process involving the use of gold wire is being investigated. The goal is to reduce the rate of defects to 5% or less. Out of the first 100 units manufactured with gold wire, only 4 are defective. True or false: Since only 4% of the 100 units were defective, we can conclude that the goal has been reached.

False

Explanation:

For the goal to be concluded as reached, the research must follow rules that will enable the proper testing of the data.

One of those is that the sample chosen must be random and the other is that the sample size must be sufficient.

The sample here is not random as it is the first 100 units and it also has an insufficient size because a sample of more than 100 will be needed to adequately test this method.

We are therefore unable to conclude that the goal has been reached, yet.
