On average, what value is expected for the f-ratio if the null hypothesis is true?.

jeyben [28]

The expected value of the f-ratio is the mean value

On average, the expected value for the f-ratio is 1.00 if the null hypothesis is true

<h3>How to determine the expected value?</h3>

From the question, we understand that the null hypothesis is true and the distribution is the F-ratio

The above scenario means that:

The variance of the top and the bottom ratio are the same

When the ratios are the same and the null hypothesis is accepted, then the expected value is 1.00

A company paid $203.00 for an item. The original price was $291.10, but this was marked down 40%. If the operating expenses

irina1246 [14]

Answer,:

Answer and Explanation: 1

Calculation for operating loss is shown below:

Break-even point in dollars = Cost + Operating expenses

Break-even point in dollars = $208.40 + (36% * $208.40)

Break-even point in dollars = $208.40 + $ 75.024

Break-even point in dollars = $283.424

Reduced price = Original price - (Original price * Mark down)

Reduced price = $292.60 - ($292.60 * 40%)

Reduced price = $292.60 - $117.04

Reduced price = $175.56

Operating loss = Break-even point in dollars - Reduced price

Operating loss = $283.424 - $175.56

Operating loss = $107.864

Calculation of absolute loss is shown below:

Absolute loss = Cost - Reduced price

Absolute loss = $208.40 - $175.56

Absolute loss = $32.84

Which set of numbers represent the lengths of the sides of a right triangle?

inna [77]

The basic deal is a^2 + b^2 = c^2
A= incorrect, 81 + 100 does not equal 121.
B= incorrect, 64 + 144 does not equal 256.
C= incorrect, 256 + 1024 does not equal 1280
This leaves D.

D must be a right triangle.
