document.write( "Question 1204105: When purchasing bulk orders of​ batteries, a toy manufacturer uses this acceptance sampling​ plan: Randomly select and test 38 batteries and determine whether each is within specifications. The entire shipment is accepted if at most 3 batteries do not meet specifications. A shipment contains 7000 ​batteries, and ​2% of them do not meet specifications. What is the probability that this whole shipment will be​ accepted? Will almost all such shipments be​ accepted, or will many be​ rejected? The probability that this whole shipment will be accepted is    enter your response here.​(Round to four decimal places as​ needed.) \n" ); document.write( "

\n" ); document.write( "\n" ); document.write( "As @Theo shown in his post, the test accepts almost all shipments  ($99.31%)
\n" ); document.write( "and rejects very few shipments  (%0.69).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It means that the test is not adequate and does not perform its functions properly.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "                         It is not surprising.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is obvious that in order for the test works adequately,  it must recognize  2%  of the control size.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If three defective batteries are admitted in the shipment,  it means that the size of the control set
\n" ); document.write( "must be about  \"3%2F0.02\" = 150 batteries.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "With the control size of  38  batteries,  3 defective batteries make the gap of  \"3%2F38\" = 0.079 = 7.8%,
\n" ); document.write( "which is too wide and admits  (passes)  too many defective shipments.\r
