The u.s. department of health and human services collected sample data for 772 males between the ages of 18 and 24. that sample

soldier1979 [14.2K]

The 99% confidence interval for the true mean is given by:

$\bar{x}\pm z_{\alpha/2} \frac{\sigma}{\sqrt{n}}$

where:

$\bar{x}$ is the sample mean = 69.7
$\sigma$ is the standard deviation = 2.8
$z_{\alpha/2}$ is the test statistics = 2.58 for for 99% confidentce interval.
n is the sample size = 772.

Therefore, the 99% confidence interval is:

$69.7\pm2.58\left( \frac{2.8}{\sqrt{772}} \right)=69.7\pm2.58(0.1008) \\ \\ =69.7-0.26\leq\mu\leq69.7+0.26 \\ \\ =69.44\leq\mu\leq69.96$

The surface area of a solid is 10 square feet. The dimensions of a similar solid are

maxonik [38]

Answer:

90 ft²

Step-by-step explanation:

Given the sides of similar figures in the ratio a : b, then

ratio of areas = a² : b²

Here ratio of sides = 1 : 3 , thus

ratio of areas = 1² : 3² = 1 : 9

That is the surface area of the new solid is 9 times the first

SA = 9 × 10 = 90 ft²

The sum of a number and three more than twice that number is 27 .what is the smaller number ?

satela [25.4K]

number - N

The sum of a number and three more than twice that number is 27.

N + (2N + 3) = 27

what is the smaller number ?

N + 2N + 3 = 27

3N = 27 - 3

3N = 24

N = 8

Check

N + (2N + 3) = 27 = 8 + (2x8 + 3) = 8 + 16 + 3 = 27
