Answer:

The marginal error is 2.355

Confidence interval is $(34.645,\ 39.355)$

The LB and UB are 34.645 and 39.3555 respectively.

Step-by-step explanation:

Consider the provided information.

n = 49, s = 8.2 c = 95%and $\bar x=37$

Degree of freedom is: n-1 = 49-1 = 48.

$\alpha =\frac{1-c}{2}= \frac{1-0.95}{2}\\\alpha = \frac{0.05}{2}= 0.025$

From the table $t_{\alpha /2}=2.010635$

Marginal error is:

$E=t_{\alpha /2}\times \frac{s}{\sqrt{n}}$

$E=2.0106\times \frac{8.2}{\sqrt{49}}$

$E=2.0106\times \frac{8.2}{7}$

$E=2.0106\times 1.171$

$E=2.355$

Hence, the marginal error is 2.355.

Part (B)

95% confidence interval estimate

$(\bar x-E,\ \bar x+E)$

$(37-2.355,\ 37+2.355)$

$(34.645,\ 39.355)$

Thus, the LB and UB are 34.645 and 39.3555 respectively.

I need help with this I need shown work too it won’t count if I am not showing my work

iogann1982 [59]

The answer is 7x + 3

First, you have 3x-1 + 2x+1
Combine like terms and the 1’s cancel each other out. You are left with 5x.

Then, you add x+2 + x+1
Combine like terms and you have 2x+3

Add 5x + 2x+3 and you have 7x +3

I’m bad at explaining, so here are the steps.
