Ray Of Light [21]
<h3>Total approximately 16 boxes of flooring will be needed in Stanley's living room. </h3>

Step-by-step explanation:

Here the given question is <u>incomplete</u>.

Stanley is having wood flooring installed in his living room. The installer has used 10 1/2 boxes of flooring on 2/3 of the room. How many total boxes of flooring will be needed for Stanley's living room?

The number of boxes used in the two third of room = 10 (\frac{1}{2} )   = 10.5 boxes

So, (\frac{2}{3} ) room  =   10. 5 boxes

So, 1 room  = 10.5 \times (\frac{3}{2} )  = 15.75 \approx 16

So, total approximately 16 boxes of flooring will be needed in Stanley's living room.

Julli [10]

Answer:

0.071,1.928

Step-by-step explanation:

                                                Downtown Store   North Mall Store

Sample size   n                             25                        20

Sample mean \bar{x}                         $9                        $8

Sample standard deviation  s       $2                        $1

n_1=25\\n_2=20

\bar{x_1}=9\\ \bar{x_2}=8

s_1=2\\s_2=1

x_1-x_2=9-8=1

Standard error of difference of means = \sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}

Standard error of difference of means = \sqrt{\frac{2^2}{25}+\frac{1^2}{20}}

Standard error of difference of means = 0.458

Degree of freedom = \frac{\sqrt{(\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}})^2}{\frac{(\frac{s_1^2}{n_1})^2}{n_1-1}+\frac{(\frac{s_2^2}{n_2})^2}{n_2-1}}

Degree of freedom = \frac{\sqrt{(\frac{2^2}{25}+\frac{1^2}{20}})^2}{\frac{(\frac{2^2}{25})^2}{25-1}+\frac{(\frac{1^2}{20})^2}{20-1}}

Degree of freedom =36

So, z value at 95% confidence interval and 36 degree of freedom = 2.0280

Confidence interval = (x_1-x_2)-z \times SE(x_1-x_2),(x_1-x_2)+z \times SE(x_1-x_2)

Confidence interval = 1-(2.0280)\times 0.458,1+(2.0280)\times 0.458

Confidence interval = 0.071,1.928

Hence Option A is true

Confidence interval is  0.071,1.928
