Answer:

upper control limit = 13.34

Step-by-step explanation:

The c-chart is used to check the change in the number of recorded calls per day

First find out the center line

c = sum of recorded calls/number of days

c = (3 + 0 + 8 + 9 + 6 + 7 + 4 + 9 + 8)/9

c = 54/9

c = 6

The upper control limit for 3σ is

upper control limit = c + 3√c

upper control limit = 6 + 3√6

upper control limit = 13.34

Therefore, the upper control limit for the 3-sigma c-chart is 13.34.

In order to estimate the mean amount of time computer users spend on the internet each month, how many computer users must be s

Sladkaya [172]

Answer:

The minimum sample size required is 5,499 computer users.

The major obstacle is that it is a big sample size if it is a small organization wanting to perform it.

Step-by-step explanation:

We need to calculate a sample size in order to have 95% confidence interval with 12 minutes of witdth.

So, we have that the difference between the upper limit and the lower limit is 12:

$UL-LL=12$

$(\mu+z*\sigma/\sqrt{n})-(\mu-z*\sigma/\sqrt{n})=12\\\\2z\sigma/\sqrt{n}=12\\\\\sqrt{n}=(1/6)*z\sigma\\\\n=(1/36)z^2\sigma^2$

For a 95% CI, the value of z is 1.96. The standard deviation is 227.

$n=z^2\sigma^2/36=(1.96)^2*(227)^2/36=3.8416*51,529/36=5498.72\\\\n=5499$

The minimum sample size required is 5,499 computer users.

Answer:

B. x = 6

Explanation:

$\rightarrow \sf x^2 = 36$

$\rightarrow \sf x= \pm \sqrt{36}$

$\rightarrow \sf x= \pm 6$

$\rightarrow \sf x= +6, \ -6$

<u>As asked for positive, (+)</u>

$\rightarrow \sf x = 6$
