Hosiah is a pottery manufacturer. Past records of his production revealed that 10 % of output of coffee mugs were defective in some way and had to be sold off as rejects. Hosiah has recently introduced some new quality control procedures. In order to assess the effectiveness of these procedures, the line manager takes a random sample of 100 of the coffee mugs and examine them. He finds 7 defectives. On the basis of this evidence alone, has there been a significant improvement in the quality of the mugs? Use the 1% level of significance
