Suppose that a manufacturer of electronic computer chips classifies each chip as either defective or non defective. Each hour 100 electronic chips are randomly selected from a very large batch of chips and tested for possible defectiveness. The file P20_16.xlsx lists the number of defective chips (out of the 100 sampled) found during each of 25 hours of production. Based on the given sample data, is this production process currently in control? Provide support for your conclusions.
