Answer:

[34,54]

Step-by-step explanation:

-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.

Where:

68% is the first standard deviation
95% is the second standard deviation about the mean
99.7% is the 3rd standard deviation about the mean.

-Therefore. the middle 95% interval is calculated as:

$CI=\mu+2\sigma\\\\=44\pm 2(5)\\\\=44\pm 10\\\\=[34,54]$

Hence, the interval is [34,54]

marin [14]

Answer:

25.2 minutes

Step-by-step explanation:

step 1

Find the area of the given wall

$A=(7)(6)=42\ ft^2$

step 2

we know that

You can paint 75 square feet of a surface every 45 minutes

using proportion

Find out how long it takes you to paint a surface area of 42 square feet

$\frac{75}{45}\ \frac{ft^2}{min}=\frac{42}{x}\ \frac{ft^2}{min}\\\\x=45(42)/75\\\\x=25.2\ min$
