Answer:

Step-by-step explanation:

Since population std deviation is not known, we use t critical value for testing of hypothesis.

df = 27, t critical = 1.706

b) 95% 28

df =27 and t critical = 2.052

c) 90% and 15

df =14 and t critical = 1.761

d) 95% and n =15

df =14: t critical = 2.145

Answer:

$\quad y=-\frac{2\left(-2x+9\right)}{3}$

Step-by-step explanation:

8x-6y-8x=36-8x

2. Simplify:

-6y=36-8x

3. Divide both sides by -6
