Question

7. MedTec produces aspirin and other over-the-counter drugs. The company’s bottling requirements certify that between 98 and 104 aspirin tablets must be in each bottle. Twelve samples of 200 bottles are selected. The number of bottles in each sample that do not meet production specifications are:

35, 36, 21, 10, 49, 52, 36, 36, 25, 24, 26, 15

      Is MedTec’s bottling process in control?

PLEASE PROVIDE INSTRUCTION SOLVING WITH CALCULATOR. THANKS!

Answer 1

1	35	200
2	36	200
3	21	200
4	10	200
5	49	200
6	52	200
7	36	200
8	36	200
9	25	200
10	24	200
11	26	200
12	15	200
Total	365	2400

=365/2400 =0.1521.

=1-0.1521=0.8479

n=200

(LCL,UCL) = (,)

                By calculating the above values we get

                   =(0.2282,0.0758)
