Answer:

80% Confidence interval: (0.4603,0.7397)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = MD = 0.60 points

Sample size, n = 9

Sample variance = 0.09

Sample standard Deviation =

$=\sqrt{\text{Sample Variance}} = \sqrt{0.09} = 0.3$

80% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 8 and}~\alpha_{0.20} = \pm 1.397$

$0.60 \pm 1.397(\frac{0.3}{\sqrt{9}} ) = 0.60 \pm 0.1397 = (0.4603,0.7397)$

2-3x=-6 solve the ecuation<br> <img src="https://tex.z-dn.net/?f=2%2F-3x%3D-6" id="TexFormula1" title="2/-3x=-6" alt="2/-3x=-6"

Mkey [24]

Answer:

2-3x=-6

We simplify the equation to the form, which is simple to understand
2-3x=-6

We move all terms containing x to the left and all other terms to the right.
-3x=-6-2

We simplify left and right side of the equation.
-3x=-8

We divide both sides of the equation by -3 to get x.
x=2.66666666667

God bless you and have a beautiful rest of the day!
