Naddik [55]

Answer:

The sample 2 has a lowest value of SE corresponding to the least sample variability.

Step-by-step explanation:

As the value of the sample means and standard deviations are not given, as similar question is found online from which the values of data is follows

The data is as attached with the solution. From this data

Sample 1 has a mean of 34 and a SE of 5

Sample 2 has a mean of 30 and a SE of 2

Sample 3 has a mean of 26 and a SE of 3

Sample 4 has a mean of 38 and a SE of 5

As per the measure of the sample variability is linked with the value of SE or standard error. Which is lowest in the case of sample 2 .

So the sample 2 has a lowest value of SE corresponding to the least sample variability.

Angelina_Jolie [31]

Answer:

2x -16

Step-by-step explanation:

The area of each rectangle is the product of its length and width. The shaded area is the difference between the areas of the outside rectangle and the inside rectangle.

shaded area = (2x -1)(x +6) -(2x +5)(x +2)

= (2x^2 +11x -6) -(2x^2 +9x +10)

= (2 -2)x^2 +(11 -9)x +(-6 -10)

= 2x -16 . . . . . area of the shaded region

Explain why the slope b of the least-squares line always has the same sign (positive or negative) as the sample correlation coef

rodikova [14]

Answer:

b = r(sy/sx)

Step-by-step explanation:

The sign of the slope Coefficient and the correlation are the same because both the slope and correlation Coefficient evaluates the changes in one variable with respect to the other . A decrease in y as x increases will result in a negative slope value and also a negative correlation Coefficient. While increase in x which results in the increase in y imvariable will result in a positive correlation Coefficient value and r value.

Slope, b = correlation Coefficient,r (Sy /Sx)

Sx = standard deviation of x values

Sy = standard deviation of Y Values

Work must be shown for this problem. Solve for x. Round answers to the nearest hundredth (2 decimal places).

mario62 [17]

Answer:

Around 16.73 feet

Step-by-step explanation:

The sine of an angle is the length of the opposite side divided by the length of the hypotenuse. Therefore:

$\sin 42 = \dfrac{x}{25} \\\\x=25\cdot \sin 42\approx 16.73$

Hope this helps!
