Acell phone manufacturer inspects the video display on each color phone to verify that the screen can display all colors with the brilliance their customers have come to expect. each phone is turned on, run through a self-test procedure, and classified as either acceptable or unacceptable based on test performance. based on historical data, the manufacturer produces 0.1 percent defective displays. if they inspect 5000 phones each day for the next 10 days, what are the upper and lower control limits for their control chart if their sample mean mirrors their historical process average?

The answer is 0.002341 and 0.000000

Explanation

From the question stated we recall the following:

Let us find the lower and upper and control limits for their chart control if their mean sample mirrors their historical process average?

Now,

The number of sample size n =5000

The number of sample k =10

The total number of observations = n x k = 5000 x 10 = 50000

The proportion defective displays p = 0.1% which is =0.001

The standard deviation, Sp = √p (1-p)/n = √0.001 x (1-0.001)/5000 =0.000447

The Upper control limit is UCL = p+3 x Sp =0.001+3 x 0.000447 =0.002341

The Lower control limit is UCL = p -3 x Sp = 0.001 - 3 x 0.000447 = -0.000341 which is 0

Therefore the LCL is 0 which is seen as negative

in 2001, dell computer became the world’s largest personal computer vendor, continuing to

gain market share and post profits in an industry struggling with slumping sales and billions of

dollars in losses. dell sells 90% of its pcs directly to the final customer, largely bypassing the

reseller channel that accounts for most of the world’s pc sales. this direct customer relationship

is the key to dell’s business model, and provides distinct advantages over the indirect sales

model. dell’s direct relationship with the customer allows it to tailor its offerings to customer

needs, offer add-on products and services, and use the internet to offer a variety of customer

services. in addition, dell’s pcs are built to customers’ specifications upon receipt of an order,

giving dell additional advantages over indirect pc vendors who must try to forecast demand and

ship products based on those forecasts. dell’s direct sales and build-to-order model has achieved

superior performance in the pc industry in terms of inventory turnover, reduced overhead, cash

conversion, and return on investment (kraemer, et al., 2000).
