Answer:

a) Upper Control Limit = 0.10

   Lower Control Limit = 0.01

b) The tech assistance process is stable and in control.

Step-by-step explanation:

Given - After a number of complaints about its tech assistance, a

            computer manufacturer examined samples of calls to determine

            the frequency of wrong advice given to callers. Each sample

            consisted of 100 calls.

SAMPLE             1   2   3   4   5   6   7   8   9  10 11 12 13 14 15 16

Number of errors 5  3   5   7   4   6   8   4   5    9   3   4   5   6   6   7

To find - a. Determine 95 percent limits.

              b. Is the tech assistance process stable (i.e., in control)

Proof -

z = 95% confidence interval

  = 1.96

⇒z = 1.96

Proportion of defects,P = total defectives/total observations

                                     = 0.0544

⇒P = 0.0544

Now,

Q = 1-P

   = 0.9456

⇒Q = 0.9456

Now,

Average sample size, N = 100

Standard deviation = [tex]\sqrt{\frac{P.Q}{N} }[/tex]

                             = 0.0227

Now,

Upper Control Limit = P + z(Standard deviation)

        = 0.0988

⇒Upper Control Limit = 0.0988 ≈ 0.10

And

Lower Control Limit = P - z(Standard deviation )

       = 0.0099

⇒Lower Control Limit = 0.0099 ≈ 0.01

∴ we get

Upper Control Limit = 0.10

Lower Control Limit = 0.01

b.)

Now,

it is clear that the fraction defective values are wit in upper an lower control limits.

So, The tech assistance process is stable and in control.

Answer:

Subtract 58-30 and add a 2:28. And Subtract 2:58-2:30

Step-by-step explanation:

Answer:

One pound can be written as 1.0 pounds, and moving the decimal place one place to the left gives you 0.10 pound, which is equal to one tenth of a pound. Convert 16 oz. to one sixteenth of an ounce by moving the decimal one place to the left.

Answer:

0.2835 = 28.35% probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals

Step-by-step explanation:

Mean during a time period means that we use the Poisson distribution.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

It is estimated that an average person makes four visits a year to doctors' offices and hospitals.

A year has 12 months, which means that the monthly mean is [tex]\mu = \frac{4}{12} = \frac{1}{3}[/tex]

What is the probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals?

This is:

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

In which

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-(\frac{1}{3})}*(\frac{1}{3})^{0}}{(0)!} = 0.7165[/tex]

[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.7165 = 0.2835[/tex]

0.2835 = 28.35% probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals

Answer:

Adter ate [tex]\frac{1}{4}[/tex] of the remaining pie.

Step-by-step explanation:

equation:

⇒ [tex]\frac{3}{4} - \frac{1}{6}[/tex]

when subtracting fractions, make sure both denominators are the same, to do this, multiply the first fraction by 3 and the second fraction by 2

⇒ [tex]\frac{3}{4} x 3 - \frac{1}{6} x 2[/tex]

⇒ [tex]\frac{9}{12} - \frac{6}{12}[/tex]

solve:

⇒ [tex]\frac{9}{12} - \frac{6}{12}[/tex]

⇒ [tex]\frac{3}{12}[/tex]

simplify:

⇒ [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

The area of the circle is 531.14 square unis

Step-by-step explanation:

Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]

where r is the radius of the circle

Given that the diameter of the circle = 26 units, the radius can be determined by;

r = [tex]\frac{diameter}{2}[/tex]

 = [tex]\frac{26}{2}[/tex]

r = 13 units

So that,

Area of the circle = [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]

                             = [tex]\frac{22}{7}[/tex] x 169

                             = 531.1429

The area of the circle is 531.14 square unis.

Answer: D. [tex]y=\frac{1}{9} x^{2}[/tex]

Step-by-step explanation: The smaller the coefficient of a fraction by the quadratic function (the x squared value), the more narrow the graph becomes. 1/4 is larger than 1/9 and the other two whole numbers are still larger than 1/9. Even though -1 is less than 1/9, this only makes the graph flip, not make it any more narrow. Fractions are what squeeze graphs, negatives do not make a difference (i.e. -1/4 is the same size of narrowness as 1/4).

Answer:

8876-(3653 +2375)

Step-by-step explanation:

So your total is 8876. On the first and the second level of the game you scored 3653 and 2375. But when you where done playing the third level your total from all of the levels ended up to be 8876. So if you wanted to find how much points you got on level 3, then you would add 3653 + 2375, then suntract the total of that from 8876.
