Suppose that you collect data for 15 samples of 30 units each, and find that on average, 2.5 percent of the products are defecti

Korvikt [17]

Answer:

The UCL is $UCL = 0.054$

The LCL is $LCL \approx 0$

Step-by-step explanation:

From the question we are told that

The quantity of each sample is n = 30

The average of defective products is $p = 0.025$

Now the upper control limit [UCL] is mathematically represented as

$UCL = p + 3 \sqrt{\frac{p(1-p)}{n} }$

substituting values

$UCL = 0.025 + 3 \sqrt{\frac{0.025 (1-0.025)}{30} }$

$UCL = 0.054$

The upper control limit (LCL) is mathematically represented as

$LCL = p - 3 \sqrt{\frac{p(1-p)}{n} }$

substituting values

$LCL = 0.025 - 3 \sqrt{\frac{0.025 (1-0.025)}{30} }$

$LCL = -0.004$

$LCL \approx 0$
