Answer:

the populations from which the samples were drawn have different standard deviations

Step-by-step explanation:

Given that the assumption of homogeneity of variance is the same as the assumption of the independent samples t-test which asserted that all comparison groups possess the same variance

Therefore, if the homogeneity of variance assumption is violated in an independent groups t-test, this means "the populations from which the samples were drawn have different standard deviations."

Gnesinka [82]
In 2 2/3 months you ran 76 miles.
To know how many miles you ran each month, you can simply use cross multiplication as follows:
number of miles per month= (76) / (2 2/3)
= 28.5 miles

How do you put f(8)=-1,f(6)=0 into point slop form?​
Mademuasel [1]

Answer:

y + 1 = -1/2(x - 8)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Point-Slope Form: y - y₁ = m(x - x₁)  

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

f(8) = -1 → Coordinate (8, -1)

f(6) = 0 → Coordinate (6, 0)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute [SF]:                    m=\frac{0+1}{6-8}
  2. Add/Subtract:                      m=\frac{1}{-2}
  3. Simplify:                               m=\frac{-1}{2}

<u>Step 3: Write Function</u>

<em>Substitute into general form.</em>

  • Point 1: y + 1 = -1/2(x - 8)
  • Point 2: y = -1/2(x - 6)

Which of the following represents the correct calculation of the sampling interval?
Goshia [24]

Answer:

The correct answer is

d. Sampling Interval = Population size ÷ Sample size.

Step-by-step explanation:

According to Johnstone et al., (2014) "<em>Once the auditor has determined the appropriate sample size, a sampling interval is calculated by dividing the population size by the sample size.</em>"

Thus,

Sampling Interval = Population size ÷ Sample size.

max2010maxim [7]

Answer:

Step-by-step explanation:

d = c/pi

so d = 62.8/pi

    d = 62.8/pi or appr 19.99in

r = d/2

so r = 62.8/2pi or 31.4/pi appr 19.99/2

a = \pi  r^{2}

so

a = \pi *(31.4/\pi)^2

then

a = 985.96/pi

so

a = approximately 313.84

answer is rowan
