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

with new selling incentive. 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.
a. Develop the appropriate null and alternative hypotheses.
b. What is the Type I error in this situation? What are the consequences of making this error?
c. What is the Type II error in this situation? What are the consequences of making this error?

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.

Find the value of the expression 0.5^10/0.5^7
SIZIF [17.4K]

Answer:

The solution is:

  • \frac{0.5^{10}}{0.5^7}=0.125

Step-by-step explanation:

Given the expression

0.5^{10}\div 0.5^7

Solving

\frac{0.5^{10}}{0.5^7}

\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

so

\frac{0.5^{10}}{0.5^7}=0.5^{10-7}

\mathrm{Subtract\:the\:numbers:}\:10-7=3

=0.5^3

=0.125        ∵ 0.5^3=0.125

Therefore, the solution is:

\frac{0.5^{10}}{0.5^7}=0.125

Geometry area question. Please help!
timurjin [86]
You can calculate polygon area with only apothem OR side length.

apothem only
area = apothem^2 * 6 * tan (180/6)
area = 10.4^2 * 6 * 0.57735
area = 108.16 * <span> <span> <span> 3.4641 </span> </span> </span>
area = <span> <span> <span> 374.677056 </span> </span> </span> square yards

side length only
area = 6 * 12^2 * / 4*tan(30)
area = 864 / 4 * 0.57735
area = 864 / <span> <span> <span> 2.3094 </span> </span> </span>
area = <span> <span> <span> 374.1231488698 </span> </span> </span> square yards

If apothem and side length were given with more precision, the answers would be closer.

\bf \textit{simmetry identities}\\\\&#10;sin(-\theta)=-sin(\theta)\\\\&#10;-------------------------------\\\\&#10;sin(-\theta)=\cfrac{1}{5}\implies -sin(\theta)=\cfrac{1}{5}\implies sin(\theta)=\cfrac{-1}{5}\cfrac{\leftarrow opposite=b}{\leftarrow hypotenuse=c}&#10;\\\\\\&#10;c^2=a^2+b^2\implies \pm\sqrt{c^2-b^2}=a\implies \pm\sqrt{5^2-(-1)^2}=a&#10;\\\\\\&#10;\pm\sqrt{24}=a\implies \pm2\sqrt{6}=a

so. hmm which is it? the +/- ?   well, neverminding for a second, the value of tangent, just looking at the sign, the tangent is positive,

tangent = opposite/adjacent.... so that only happens, when both are the same sign, + or - both

now, we know the sine is -1/5.. if the sine is negative, the cosine also has t to be negative, so we'd use the -2√(6) = a

thus     \bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\implies cos(\theta)=\cfrac{-2\sqrt{6}}{5}
