Answer:

Step-by-step explanation:

Hello!

You need to construct a 95% CI for the population mean of the length of engineering conferences.

The variable has a normal distribution.

The information given is:

n= 84

x[bar]= 3.94

δ= 1.28

The formula for the Confidence interval is:

x[bar]± $Z_{1-\alpha/2}$ *(δ/n)

Lower bound(Lb): 3.698

Upper bound(Ub): 4.182

Error bound: (Ub - Lb)/2 = (4.182-3.698)/2 = 0.242

I hope it helps!

Solve for x ! problems attached please help!!

Answer:

7. $x\le 8$

8. $x\le 1.7$

9. $-0.2\le x\le 2$

10. $3< x\le 4$

Step-by-step explanation:

7. Solve for x:

$4x+7-x\le 31$

Separate variable and numbers into different sides of inequality:

$4x-x\le 31-7\\ \\3x\le 24$

Divide the inequality by 3:

$x\le 8$

8. Solve for x:

$2(x-3)+8x\le 11$

Eliminate the brackets:

$2x-6+8x\le 11$

Separate variable and numbers into different sides of inequality:

$2x+8x\le 11+6\\ \\10x\le 17$

Divide the inequality by 10:

$x\le 1.7$

9. Solve for x:

$-7x\le 3x+2\le 8$

Solve two inequalities $-7x\le 3x+2$ and $3x+2\le 8$ separately:

$-7x\le 3x+2\\ \\3x+2\ge -7x\\ \\3x+7x\ge -2\\ \\10x\ge -2\\ \\x\ge -0.2$

and

$3x+2\le 8\\ \\3x\le 8-2\\ \\3x\le 6\\ \\x\le 2$

So,

$-0.2\le x\le 2$

10. Solve for x:

$8$

Add 1:

$8+1$

Divide by 3:

$3< x\le 4$
