g The downtime per day for a computing facility has mean 4 hours and standard deviation 0.9 hour. What assumptions must be true
Sedaia [141]

Answer:

To obtain a valid approximation for probabilities about the average daily downtime, either the underlying distribution(of the downtime per day for a computing facility) must be normal, or the sample size must be of 30 or more.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

In this question:

To obtain a valid approximation for probabilities about the average daily downtime, either the underlying distribution(of the downtime per day for a computing facility) must be normal, or the sample size must be of 30 or more.

What is the length of the line segment with endpoints (11, −4) and (−12, −4
RUDIKE [14]

Answer:

23 units

Step-by-step explanation:

Use the distance formula: d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

Plug in the 2 points:

d = \sqrt{(-12 - 11)^2 + (-4 + 4)^2}

d = \sqrt{529}

d = 23

So, the distance is 23 units

Suppose there are three balls in a box. On one of the balls is the number 1, on another is the number 2, and on the third is the
quester [9]

Step-by-step explanation:

a) X is a discrete uniform distribution. As the number of outcomes is only 3.

b) sum is at least 4

X ≥ 4

i.e  (1,3) or (2,3)

probability of X ≥ 4 is 2/3

2/3= 0.667

66.7 % is the probability of the outcome to have  a sum at least 4.

c) The 3 likely outcome of X

<em>(1,2) where X ; </em> 1+2=3

<em>(1,3) where X ;</em> 1+3=4

<em>(2,3) where X ;</em>  2+3=5

Mean = 3+4+5/ 3

Mean = 4
