Answer:

Step-by-step explanation:

It would be answer b, because if you were to solve this, then this is how you would do it (in the most effecient way):

2.5x + 1.2 = 1.2x + 4.2

2.5x + 1.2 - 1.2 = 1.2x + 4.2 - 1.2

2.5x = 1.2x + 3

2.5x - 1.2x = 1.2x - 1.2x + 3

1.3x = 3

1.3x/1.3 = 3/1.3

x = 3/1.3

Answer: a) 0.84 b) 0.67 c) 1.28

Step-by-step explanation:

Using the standard normal distribution table for z-value , we have

(a) The value of $z_{\alpha}$ would result in a 80% one-sided confidence interval : $z_{(1-0.80)}=z_{0.20}=0.8416\approx0.84$

(b) The value of $z_{\alpha}$ would result in a 85% one-sided confidence interval : $z_{(1-0.85)}=z_{0.25}=0.6744897\approx0.67$

(c) The value of $z_{\alpha}$ would result in a 90% one-sided confidence interval : $z_{(1-0.90)}=z_{0.10}=1.2815515\approx1.28$
