Production records indicate that in normal operation for a certain electronic component, 93% have no faults, 5% have one fault, and 2% have more than one fault. For a random sample of 500 of these components from a week's output, 458 were found to have no faults, thirty to have one fault, and twelve to have more than one fault. Test at the 5% level the null hypothesis that the quality of the output from this week conforms to the usual pattem.
