7. These values represent the expected number of paintings a person will produce over the next 10 days. 0, 0, 0, 1, 1, 1, 2, 2,

Natasha_Volkova [10]

The mean of a dataset is the average of the dataset.

The mean is 1.5
The standard deviation is 1.58
The median remains unchanged, the mean increases, and the standard deviation decreases when 5 is increased to a larger value

The given parameters are:

$\mathbf{x = 0, 0, 0, 1, 1, 1, 2, 2, 3, 5}$

(a) Mean and Standard deviation

The mean of the dataset is calculated using:

$\mathbf{\bar x = \frac{\sum x}{n}}$

So, we have:

$\mathbf{\bar x = \frac{0+ 0+ 0+ 1+ 1+ 1+ 2+ 2+ 3+ 5}{10}}$

$\mathbf{\bar x = \frac{15}{10}}$

$\mathbf{\bar x = 1.5}$

Hence, the mean is 1.5

The standard deviation is calculated using:

$\mathbf{\sigma_x = \sqrt{\frac{\sum(x - \bar x)^2}{n - 1}}}}$

So, we have:

$\mathbf{\sigma_x = \sqrt{\frac{(0 - 1.5)^2 + (0- 1.5)^2 + (0- 1.5)^2 + (1- 1.5)^2 + (1- 1.5)^2 + (1- 1.5)^2 + (2- 1.5)^2 + (2- 1.5)^2 + (3- 1.5)^2 + (5- 1.5)^2}{10 - 1}}}$

$\mathbf{\sigma_x = \sqrt{\frac{22.5}{9}}}$

$\mathbf{\sigma_x = \sqrt{2.5}}$

$\mathbf{\sigma_x = 1.58}$

Hence, the standard deviation is 1.58

(b) When 5 is increased to a larger value

When 5 is increased:

The median remains unchanged
The mean increases
The standard deviation decreases

Answer:

The last one

Step-by-step explanation:

Because 0 < -2 -2, 0 <-4. It is not a true statement. It tell you that the middle one is wrong. The first one is wrong to because there are no equal sign.

What is x*24-34+56? And how did you get the answer?

Ilia_Sergeevich [38]

I assume you are solving for x

x*24-34+56 = 0

Start by isolating the term with x in it on one side of the equation.

To do this, we can subtract 56 and add 34 to both sides.

24x = -22

Divide both sides by 24 to complete the problem.

x= -22/24
