Hello.

Y= 2/7

Step 1: Simplify both sides of the equation.

5y+2−3(4y)=0

5y+2+−12y=0

(5y+−12y)+(2)=0(Combine Like Terms)

−7y+2=0

Step 2: Subtract 2 from both sides.

−7y+2−2=0−2

−7y=−2

Step 3: Divide both sides by -7.

−7y/−7=−2/−7

y=2/7

Have a nice day.

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,

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

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