A cell phone manufacturer inspects the video display on each color phone to verify that the screen can display all colors with t

he 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?

Answer:

<em>The answer is 0.002341 and 0.000000</em>

Explanation

<em>From the question stated we recall the following:</em>

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

<em>Now,</em>

<em>The number of sample size n =5000</em>

<em>The number of sample k =10</em>

<em>The total number of observations = n x k = 5000 x 10 = 50000</em>

<em>The proportion defective displays p = 0.1% which is =0.001</em>

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

<em>The Upper control limit is UCL = p+3 x Sp =0.001+3 x 0.000447 =0.002341</em>

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

<em>Therefore the</em> LCL is 0 which is seen as negative

Howard Weiss, Inc,. is considering building a sensitive new radiation scanning device. His managers believe that there is a prob
SpyIntel [72]

Answer:

<u>Consider the following information</u>

Probability of ATR coming up with a competitive product is 0.35

If ATR does not come up with a competitive product and H adds an assembly line, the profit is $60,000

If it adds an assembly line and ATR adds the product, the profit is $20,000

If H adds a new assembly but ATR does not come up with a competitive product, the profit is $600,000

If ATR does not enter the market, the loss for H is $120,000

<u>A) Expected value for the add assembly line option: </u>

The company would get a profit of $60,000 if ATR does not come up with a competitive product. If ATR comes up with a competitive product and H adds an assembly line, the profit is $20,000.

Probability of not coming up with a product is 0.65 (1-0.35)

Calculate the value if it does not come up with a new product line and H adds an assembly line as follows:

Value if it does not come up with a new product = 0.65 x $60,000

= $39,000

Calculate the value if it comes up with a new product line and H adds an assembly line as follows:

Value if it does come up with a new product = 0.35 x $20, 000  = $7,000

Calculate the expected value as follows:  

Expected value = S39000 + $7000

Expected value =$46,000

<u>Expected value for build new plant option: </u>

If H adds a new assembly but ATR does not come up with a competitive product, the profit is $600,000

If ATR does not enter the market, the loss for H is $120,000

Calculate the value if H adds a new assembly but ATR does not come up with a competitive product as follows:

Value if it does not come up with a new product = 0.65 x $600000

= $390, 000

Calculate the value if ATR does not enter the market:

Value if it does not compete in market = 0.35 x -$120000  = -$42, 000

Calculate the expected value as follows:  

Expected value= $390,000 - $42,000

Expected value =$348,000

The expected value of building a plant is more than the expected value of adding product line. Therefore, the best alternative is to build the plant.

<u>B) Calculation of expected value of perfect information (EVPI): </u>

EVPI = 0.65 x $600,000 + 0.35 x $120,000

EVPI = $390,000 + $42,000

EVPI =$432,000

<u>Calculation of value of return: </u>

Value of return = Value of perfect information - Maximum EMV

Value of return =$432,000 - 348,000

Value of return =$84,000

A constant-cost industry is one in which_______
tiny-mole [99]

Answer:

b.if 100 units can be produced for $100, then 150 can be produced for $150, 200 for $200, and so forth.

Explanation:

Constant-cost means the cost of producing one unit of product does not change no matter how many products each firm in the industry decide to produce.

If the cost of production is $100 for 100 units, $150 for 150 units, $200 for 200 units and so forth, it means the unit production cost is a constant $1 regardless of the quantity to be produced.

The increase in unemployment that occurs during recessions and depressions is called Group of answer choices normal unemployment
belka [17]

Answer:

cyclical unemployment.

Explanation:

Unemployment rate refers to the percentage of the total labor force in an economy, who are unemployed but seeking to be gainfully employed. The unemployment rate is divided into various types, these include;

I. Cyclical unemployment rate (CU).

II. Frictional unemployment rate (FU).

III. Structural unemployment rate (SU).

IV. Actual unemployment rate (AU).

V. Natural Rate of Unemployment (NU).

A cyclical unemployment can be defined as a type of unemployment which is typically related to changes in the business, economy or industry cycle such as recession, governmental policies etc.

Mathematically, cyclical unemployment rate can be calculated using the formula;

Cyclical \; unemployment \; rate \;  (CU) = Actual \; unemployment \; rate \; (AU) - Natural \;unemployment \; rate \; (NU)

Hence, the increase in unemployment that occurs during recessions and depressions is called cyclical unemployment
