2)- Checking all manufacturing items coming off an assembly line for defectives would be a costly and time-consuming procedure. One effective and economical method of checking for defectives involves the selection and examination of a portion of the items by a quality control engineer. The percentage of examined items that are defective is computed and then used to estimate the percentage of all items manufactured on the line that are defective. Identify the population, the sample, and a type of statistical inference to be made for this problem.
