Carpetland salespersons average $8,000 per week in sales. Steve Contois, the firm’s vice president, proposes a compensation plan

olya-2409 [2.1K]

Answer with Step-by-step explanation:

Since we have given that

Average per week in sales = $8000

Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increase the average sales per salesperson

So, the appropriate null and alternate hypothesis would be

$H_0:\mu=8000\\\\H_a:\mu>8000$

b. What is the Type I error in this situation? What are the consequences of making this error?

Type 1 error are those errors in which null hypothesis are supposed to be rejected, but it does not get rejected.

It means sales per week is greater than $8000 but in actual it is not.

c. What is the Type II error in this situation? What are the consequences of making this error?

Type 2 are error are those errors in which null hypothesis are supposed to be accepted but it get rejected.

It means average sales per week is actually $8000 but it is calculated that average sales is less than $8000.

Consider an arbitrary ellipse x 2 a 2 + y 2 b 2 = 1. (Assume a, b > 0.) (a) Find a parametrization of the ellipse using the d

uysha [10]

Answer:

α(t) = (-a*Sin(t), b*Cos (t)) where t ∈ [0, 2π]

Step-by-step explanation:

Given an arbitrary ellipse (x²/a²) + (y²/b²) = 1 (a, b > 0)

The parametrization can be as follows

x = -a*Sin(t)

y = b*Cos (t)

then

α(t) = (-a*Sin(t), b*Cos (t)) where t ∈ [0, 2π]

If t = 0

α(0) = (-a*Sin(0), b*Cos (0)) = (0, b)

If t = π/2

α(π/2) = (-a*Sin(π/2), b*Cos (π/2)) = (-a, 0)

If t = π

α(π) = (-a*Sin(π), b*Cos (π)) = (0, -b)

If t = 3π/2

α(3π/2) = (-a*Sin(3π/2), b*Cos (3π/2)) = (a, 0)

If t = 2π

α(2π) = (-a*Sin(2π), b*Cos (2π)) = (0, b)

We can see the sketch in the pic.

C.) 1600 pi cm3

When you do 10^2 you get 100 and you multiply that by the height so 16 and you get 1600.

Can you please help me with this question

Luda [366]

So we are simply adding them

we will set the denominator equal by multiplying both the numerator and denominator
then just adding the numerator while keeping the denominator. look at my work. so your answer is 5/8
