    Answer:

    The manager’s prediction is false.

    The number of defective computers approximately 928

    Step-by-step explanation:

    Number of computers produced in a month = 64000

    Number of defective computers claimed in a month = 515

    345 computers were randomly picked and 5 detectives were found.

    Using simple proportion:At every 345 computers randomly checked 5 were defective

    64000 computers will have X defectives

    X =(64000/345 )× (5/1)

    X= 927.5 approximately 928 defective computers.

    The manager’s prediction is false because there are 928 defective computers and not 515 .
