Five data entry operators work at the data processing department of the Birmingham Bank. Each day for 30 days, the number of defective records in a sample of 300 records typed by these operators has been noted, as follows:

Sample No. No. Defectives
1 8
11 7
21 17
2 4
12 5
22 13
3 19
13 16
23 6
4 10
14 3
24 6
5 12
15 12
25 13
6 9
16 8
26 11
7 11
17 13
27 15

a) Establish 3σ upper and lower control limits.

UCLp = (enter your response as a number between 0 and 1, rounded to three decimal places).

LCPp =(enter your response as a number between 0 and 1, rounded to three decimal places).

i am thinking c. sorry if im wrong .

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
