Statistics help present data precisely and draw meaningful conclusions. While presenting data, one should be aware of using adequate statistical measures.

Readers are generally interested in knowing the variability within the sample, descriptive data should be precisely summarized with SD. The use of SEM should be limited to computing CI which measures the precision of population estimate. Journals can avoid such errors by requiring authors to adhere to their guidelines.

Studying the entire population is time and resource-intensive and not always feasible; therefore studies are often done on the sample, and data are summarized using descriptive statistics. These findings are further generalized to the larger, unobserved population using inferential statistics.

For example, to understand the cholesterol levels of the population, the cholesterol levels of the study sample, drawn from the same population are measured.

Step-by-step explanation:

Answer:

Through substitution, you plug the second equation into the first equation, which would be: 2x + x - 3 = 3. Then combine like terms, which would be: 3x = 6. Divide both sides by 3 to get: x = 2. Now use this x-value in the first equation: 2 (2) + y = 3 ; 4 + y = 3. Now combine like terms, once again, to get y = -1. Therefore the solution to this system of equations is (2,-1) To verify, you will get 3 if you plug in the respective values in to the first equation.

The compositions between functions f(x) = 3 · x - 2 and g(x) = x + 1 are f[g(x)] = 3 · x + 1 and g[f(x)] = 3 · x - 1, respectively.

Let be f(x) and g(x) functions, there is a composition of the form f[g(x)], when the independent variable of function f is substituted by function g. That is to say:

The relationship between the mean and median can provide information about the shape of the distribution and the presence of outliers.

The mean and median can be either close to the same value or very different from one another, depending on the distribution of the data.

If the data is approximately symmetric, with no extreme values, then the mean and median will be close to each other. In this case, the data is evenly distributed around the central tendency of the data, so both measures provide a similar representation of the central value.

However, if the data is skewed, with one tail longer than the other, or if there are extreme values (outliers) present in the data, then the mean and median will be different.

In this case, the mean is pulled in the direction of the skew or outliers, while the median remains unaffected.

As a result, the mean may not provide an accurate representation of the central tendency of the data.

The z-score for the new player's salary is 0.59375

The z-score is a measure of how many standard deviations a value is from the mean. To find the z-score for a salary of $2.65 million, we can use the following formula:

z = (x - μ) / σ

where:

x = the salary of the new player ($2.65 million)

μ = the mean salary of professional baseball players ($2.46 million)

σ = the standard deviation of the salary ($0.32 million)

Plugging in the values, we get:

z = ($2.65 million - $2.46 million) / $0.32 million

z = ($0.19 million) / $0.32 million

z = 0.59375

Therefore, the z-score for the new player's salary is 0.59375. This means that the new player's salary is 0.59375 standard deviations above the mean salary of professional baseball players.

Answer:

-4

Step-by-step explanation:

Energy consumption is the amount of power used over time, measured in watt-hours (Wh) or kilowatt-hours (kWh). It is calculated by multiplying the power (measured in watts) by the time for which it is used.

To calculate energy consumption, you will need to know the amount of power being used and the time over which it is being used. Power is typically measured in watts (W), and energy is the product of power and time, so energy consumption is the number of watts used multiplied by the number of hours for which they are used.

For example, let's say you want to calculate the energy consumption of a light bulb that uses 60 W of power and is left on for 4 hours. The energy consumption would be:

Energy consumption = 60 W * 4 hours = 240 Wh (watt-hours)

This is the amount of energy that the light bulb used over the 4-hour period.

You can also convert watt-hours to other units of energy, such as kilowatt-hours (kWh). To do this, you would divide the watt-hours by 1,000. In the example above, the energy consumption would be 0.240 kWh.

1) When x is less than 0, multiply x by -2.

2) When x is greater than or equal to 0, multiply x by 4.

As defined by the question, x = -3. Since -3 is less than 0, you would go to scenario 1, which multiplies x (-3) by -2, giving you 6.

Answer:

y = -3/2 x + 2

Step-by-step explanation:

3x + 2y = 8

2y = -3x + 8

y = -3/2 x + 4

slope of given line = m = -3/2

Parallel lines have equal slopes.

Slope of parallel line through point (-2, 5), m = -3/2.

y = mx + b

m = -3/2

y = -3/2 + b

point: (-2, 5)

5 = (-3/2)(-2) + b

5 = 3 + b

b = 2

Equation: y = -3/2 x + 2

4x – 2y=7

3x – 3y = 15

we want to keep y by eliminating the x

so we will Multiply the top equation by 3 and the bottom equation by 4.

we will get

12x - 6y = 21

12x - 12y = 60

we subtract the equations

12x - 6y - 12x - (-12y) = 21 - 60

6y = -39 and so on

Using the center-of-gravity technique, the best site location for the new distribution center in Charlotte is determined to be at coordinates (X, Y) = (27.92, 19.08).

The center-of-gravity technique is used to find the optimal location for a facility based on the distribution of demand. In this case, we will calculate the weighted average of the coordinates (X, Y) of the three sites, with the weights being the number of weekly packages flowing to each site.

To calculate the X-coordinate of the center of gravity, we use the formula:

Xc = (X1 * W1 + X2 * W2 + X3 * W3) / (W1 + W2 + W3)

Similarly, for the Y-coordinate:

Yc = (Y1 * W1 + Y2 * W2 + Y3 * W3) / (W1 + W2 + W3)

Substituting the given values:

Xc = (16 * 26000 + 35 * 12000 + 40 * 10000) / (26000 + 12000 + 10000) ≈ 27.92

Yc = (28 * 26000 + 10 * 12000 + 18 * 10000) / (26000 + 12000 + 10000) ≈ 19.08

Therefore, the best site location for the new distribution center in Charlotte is approximately at coordinates (X, Y) = (27.92, 19.08) based on the center-of-gravity technique.

Answer:  \(\text{y} = \frac{7}{3}\text{x}-\frac{2}{3}\)

This is the same as writing y = (7/3)x - 2/3

=======================================================

Explanation:

The given equation is in y = mx+b form

m = -3/7 = slope

b = 4 = y intercept

Flip the fraction for the slope to get -7/3, and flip the sign from negative to positive to get 7/3

The original slope is -3/7 and the perpendicular slope is 7/3. These two slopes multiply to -1.

We want the perpendicular line to go through \((\text{x}_1,\text{y}_1) = (2,4)\\\\\)

We'll use the point-slope form to get...

\(\text{y} - \text{y}_1 = \text{m}(\text{x}-\text{x}_1)\\\\\text{y} - 4 = \frac{7}{3}(\text{x}-2)\\\\\text{y} - 4 = \frac{7}{3}\text{x}+\frac{7}{3}(-2)\\\\\text{y} - 4 = \frac{7}{3}\text{x}-\frac{14}{3}\\\\\text{y} = \frac{7}{3}\text{x}-\frac{14}{3}+ 4 \\\\\text{y} = \frac{7}{3}\text{x}-\frac{14}{3}+ \frac{12}{3} \\\\\text{y} = \frac{7}{3}\text{x}+\frac{-14+12}{3} \\\\\text{y} = \frac{7}{3}\text{x}-\frac{2}{3} \\\\\)

This equation has a slope of 7/3 and y intercept of -2/3.
