rusak2 [61]

Answer:

-0.67

Step-by-step explanation:

Given that :

Population mean, μ = 4.7

Sample size, n = 68

Sample mean, M = 4.3

Sample standard deviation, s = 0.6

The effect size, d can be obtained using the relation :

d = (M - μ) / s

d = (4.3 - 4.7) / 0.6

d = - 0.4 / 0.6

d = - 0.66666

d = - 0.67

Hence, effect size associated with a single-sample t test is - 0.67

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Quadratic Formula: \displaystyle x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

x² - 7x - 8

↓

<em>a</em> = 1, <em>b </em>= -7, <em>c</em> = -8

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [Quadratic Formula]:                                                  \displaystyle x=\frac{7 \pm \sqrt{(-7)^2-4(1)(-8)}}{2(1)}
  2. [√Radical] Evaluate exponents:                                                                       \displaystyle x=\frac{7 \pm \sqrt{49-4(1)(-8)}}{2(1)}
  3. [√Radical] Multiply:                                                                                           \displaystyle x=\frac{7 \pm \sqrt{49 + 32}}{2(1)}
  4. [√Radical] Add:                                                                                                 \displaystyle x=\frac{7 \pm \sqrt{81}}{2(1)}
  5. [√Radical] Evaluate:                                                                                         \displaystyle x=\frac{7 \pm 9}{2(1)}
  6. Multiply:                                                                                                             \displaystyle x=\frac{7 \pm 9}{2}
  7. Add/Subtract:                                                                                                    \displaystyle x=\frac{-2}{2}, \ \frac{16}{2}
