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.

Answer:

0.0416

Step-by-step explanation:

Given :

Sample size, n = 300

Sample mean, x = 35.5

Population mean, m = 35

Standard deviation, s = 5

The test statistic :

Zstatistic = (x - m) / s/sqrt(n)

Zstatistic = (35.5 - 35) / 5/sqrt(300)

Zstatistic = 0.5 / 0.2886751

Zstatistic = 1.732

Using the p value calculator from Zstatistic :

One tailed P value at 95% confidence interval is : 0.0416
