Aleks04 [339]

Answer:

Interval estimate for the proportion of all homeowners in the United States that hold a home equity loan lie between (.17033 , .22967 ) or 17% to 22.9%

Step-by-step explanation:

Given -

In a recent poll of 1,200 homeowners in the United States, one in five homeowners reports having a home equity loan that he or she is currently paying off.

If one in five homeowners reports having a home equity loan then for 1200 homeowners = $\frac{1200}{5}$ = 240 homeowners reports having a home equity loan.

Sample proportion $(\widehat{p})$ = $\frac{240}{ 1200}$ = 0.2

confidence coefficient = 0.99

$(\alpha)$ = 1 - confidence coefficient = 1 - 0.99 = .01

$z_{\frac{\alpha}{2}} = z_{\frac{.01}{2}}$ = 2.58

interval estimate for the proportion of all homeowners in the United States that hold a home equity loan

= $\widehat{p}\pm z_{\frac{\alpha}{2}}\sqrt\frac{{\widehat{p}( 1 - \widehat{p})}}{n}$

= $0.2\pm z_{\frac{.01}{2}}\sqrt\frac{{0.2( 1 - 0.2)}}{1200}$

= $0.2\pm 2.58\times \sqrt\frac{{0.2( 0.8)}}{1200}$

= $0.2\pm .02967$

= $(0.2 - .02967 ) , (0.2 + .02967)$

= (.17033 , .22967 )

Question 6 Multiple Choice Worth 1 points)

slavikrds [6]

Answer:

Option B) The additive inverse of -3 is +3, so

$17 -(-3) = 20.$

Step-by-step explanation:

We are given the following expression in the question:

$17 - (-3)$

Additive Inverse:

The additive inverse of a number a is the number when added to the original numbers it gives a sum of zero.
Let x be a number, then additive inverse of x is -x

$x + (-x) = 0$

Additive Inverse of -3 is 3

$-3 + (3) = -3+3 = 0$

Option B) correctly explains the given statement.

$17-(-3) = 17+3 = 20$

Opion B)

The additive inverse of -3 is +3, so

$17 -(-3) = 20.$
