On a given day, the proportion of workers from Company B who purchase a coffee from the company cafeteria is 0.62 and the proportion of workers from Company C who purchase a coffee from the company cafeteria is 0.71. A random sample of40 workers was selected from Company B and another random sample of 40 workers was selected from Company C. The proportion of workers from Company B who purchased coffee was pˆB=0.70 and the proportion of workers from Company C who purchased coffee was pˆC=0.75.

What is the correct unit of measure for the mean of the sampling distribution of pˆB−pˆC ?

Answers

Answer 1

Answer:

The sampling distribution of the mean will have no unit.

Explanation:

Given that:

P(B) = 0.62

P(C) = 0.71

pˆB = 0.70

pˆC = 0.75

The expression : pˆB−pˆC

Represents the difference in mean of the sample distribution :

The proportions pˆB = 0.70 and pˆC = 0.75 are obtained as (number of workers who purchased coffee / total number of workers). The ratio above due to division will have no units.

The graph of the continuous function f consists of three line segments, as shown in the figure above. What is the average value of f on the interval [−1,6] ?

Answers

Answer:

The average value of the function on the interval [-1, 6] is [tex]2.\overline{1428571}[/tex]

Explanation:

The given

The average of a function is the height, 'h', of a rectangle with a width equivalent to the given interval and an area equivalent to the area of the function

The area under the graph of the function between the interval [-1, 6] consist of two right triangles and a rectangle and it is therefore given as follows;

The area. A = 1/2 × (0 - (-1)) × 2 + 2 × (6 - 0) + 1/2 × (4 - 2) × (6 - 4) = 15

The width of the rectangle, w = (6 - (-1)) = 7

w = 7

The area of the rectangle = h × w = A = 15

∴ The average value of the function, f = h = A/w = 15/7 = [tex]2.\overline{1428571}[/tex]

The regions bounded by the graphs of y=x2 and y=sin2x are shaded in the figure above. What is the sum of the areas of the shaded regions?

Answers

Answer:

The sum of the area of the shaded regions = 0.248685

Explanation:

The sum of the area of the shaded region is given as follows;

The point of intersection of the graphs are;

y = x/2

y = sin²x

∴ At the intersection, x/2 = sin²x

sinx = √(x/2)

Using Microsoft Excel, or Wolfram Alpha, we have that the possible solutions to the above equation are;

x = 0, x ≈ 0.55 or x ≈ 1.85

The area under the line y = x/2, between the points x = 0 and x ≈ 0.55, A₁, is given as follows

1/2 × (0.55)×0.55/2 ≈ 0.075625

The area under the line y = sin²x, between the points x = 0 and x ≈ 0.55, A₂, is given using as follows;

[tex]\int\limits {sin^n(x)} \, dx = -\dfrac{1}{n} sin^{n-1}(x) \cdot cos(x) + \dfrac{n-1}{n} \int\limits {sin^{n-2}(x)} \, dx[/tex]

Therefore;

[tex]A_2 = \int\limits^{0.55}_0 {sin^2x} \, dx = \dfrac{1}{2} \left [x -sin(x) \cdot cos(x) \right]_0 ^{0.55}[/tex]

∴ A₂ =1/2 × ((0.55 - sin(0.55)×cos(0.55)) - (0 - sin(0)×cos(0)) ≈ 0.0522

The shaded area, [tex]A_{1 shaded}[/tex] = A₁ - A₂ = 0.075625 - 0.0522 ≈ 0.023425

Similarly, we have, between points 0.55 and 1.85

A₃ = 1/2 × (1.85 - 0.55) × 1/2 × (1.85 - 0.55) + (1.85 - 0.55) × 0.55/2 = 0.78

For y = sin²x, we have;

[tex]A_4 = \int\limits^{1.85}_{0.55} {sin^2x} \, dx = \dfrac{1}{2} \left [x -sin(x) \cdot cos(x) \right]_{0.55} ^{1.85} \approx 1.00526[/tex]

The shaded area, [tex]A_{2 shaded}[/tex] = A₄ - A₃ = 1.00526 - 0.78 ≈ 0.22526

The sum of the area of the shaded regions, ∑A = [tex]A_{1 shaded}[/tex] + [tex]A_{2 shaded}[/tex]

∴ A = 0.023425 + 0.22526 = 0.248685

The sum of the area of the shaded regions, ∑A = 0.248685
