Which of the following is NOT an observation about critical​ values? Choose the correct answer below. A. The number is a critica
Bess [88]

The correct options are;

A. The number z_α/2 is a critical value that corresponds to an area of 1 − α/2 to its left.

B. The number z_α/2 is a critical value that is a z score with the property that

it separates an area of α/2 in the right tail of the standard normal distribution.

C. A critical value is the number on the borderline separating sample statistics that are likely to occur from those that are unlikely to occur.

D. A critical value is the area in the right-tail region of the standard normal curve.

Answer:

Option D: A critical value is the area in the​ right - tail region of the standard normal curve.

Step-by-step explanation:

A critical value is defined as the line on a graph that makes that graph split into sections.

Now, either one or two of the sections split will fall into the “rejection region“.

So, if the test value falls into the rejection region, it means we will reject the null hypothesis.

Looking at the options given, options A, B & C are possible observations that we could deduce about critical values based on the definition given above.

Option D is not an observation because the critical value is what denotes the z-score with an area of alpha in the right tail region

Joint-Serve Prosthetics spends 43% of its total expenses for payroll. It increased its total expenses when it spent $250,000 for
Leni [432]
Answer: $2,150,000

Explanation: Let

T = Total expenses of Joint-Serve

Then, before the company acquired robotic assemblers, the expenses allocated for payroll is given by

Expenses for Payroll = 43% of Total Expenses
Expenses for Payroll = 0.43T     (1)
(Because 43% = 0.43)

Because the total expenses increased by $250,000 after spending for robotic assemblers, the total expenses = T + 250,000

So, the payroll expense is now calculated as

Expenses for Payroll = 38% of Total Expenses
Expenses for Payroll = 0.38(T + 250,000)     (2)
(Because 38% = 0.38 and total expenses = T + 250,000)

By comparing equations (1) and (2),

0.43T = 0.38(T + 250,000)
\\ 0.43T = 0.38T + 0.38(250,000)
\\ 0.43T = 0.38T + 95,000
\\ 0.43T - 0.38T = 95,000
\\  \frac{0.05T}{0.05}  =  \frac{95,000}{0.05} 
\\ \boxed{T = \$ 1,900,000}

Thus, the total expense before the purchase of robotic assemblers is T = $ 1,900,000. Therefore, the total expense after purchasing the robotic assemblers is T + 250,000 = 1,900,000 + 250,000 = $2,150,000

The sum of the interior angle measures of a triangle is 180'. Angle B is three times the measure of angle A. Angle C is 52. Find
vovikov84 [41]

Answer:

Angle A = 32

Angle B = 96

Angle C = 52

Step-by-step explanation:

180 - 52 = 128

128 / 4 = 32

Angle A = 32

Angle B = 3 x 32 = 96

Angle C = 52

Check:

32 + (3 x 32) + 52 = 180

What is the equation of the graphed function?
masya89 [10]
The correct answer is A.) f(x)=\frac{-1}{3}x+1

This is because using slope intercept form (y=mx+b), we can solve.

m = slope
b= y-intercept

If you look at the graph, you can see the line crosses they y-axis at 1.

And if you follow the line using rise over run, you find that it is 1/3.
But because it is a negative line, it makes the slope negative.

Hope this helps!
