Answer:

85%(estimated)

Step-by-step explanation:

150-22=128

changed ÷ original x 100%

128 ÷ 150 x 100%

≈ 85%

Consider the following. 12, 7, 18, 23, 24, 27 Compute the population standard deviation of the numbers. (Round your answer to tw

avanturin [10]

Answer:

(a) $\sigma = 7.04$

(b) $\sigma = 14.1$

(c) The population standard deviation is multiplied by k

Step-by-step explanation:

Given

$Dataset: 12, 7, 18, 23, 24, 27$

Solving (a): The population standard deviation

Start by calculating the mean

$\mu = \frac{\sum x}{n}$

$\mu = \frac{12+7+18+23+24+27}{6}$

$\mu = \frac{111}{6}$

$\mu = 18.5$

The population standard deviation is:

$\sigma = \sqrt{\frac{\sum(x - \mu)^2}{n}}$

This gives:

$\sigma = \sqrt{\frac{(12-18.5)^2 + (7 - 18.5)^2 + (18-18.5)^2 + (23-18.5)^2 + (24 - 18.5)^2 + (27 - 18.5)^2}{6}}$

$\sigma = \sqrt{\frac{297.5}{6}}$

$\sigma = \sqrt{49.5833}$

$\sigma = 7.04$

Solving (b): Double the dataset and calculate the new population standard deviation

The new dataset is:

$Dataset: 24, 14, 36, 46, 48, 54$

Start by calculating the mean

$\mu = \frac{\sum x}{n}$

$\mu = \frac{24+ 14+ 36+ 46+ 48+ 54}{6}$

$\mu = \frac{222}{6}$

$\mu = 37$

The population standard deviation is:

$\sigma = \sqrt{\frac{\sum(x - \mu)^2}{n}}$

This gives:

$\sigma = \sqrt{\frac{(24-37)^2 +(14-37)^2 +(36-37)^2 +(46-37)^2 +(48-37)^2 +(54-37)^2}{6}}$

$\sigma = \sqrt{\frac{1190}{6}}$

$\sigma = \sqrt{198.33}$

$\sigma = 14.1$

Solving (c): What happens when the dataset is multiplied by k

In (a), we have:

$\sigma = 7.04$

In (b), when the dataset is doubled,

$\sigma = 14.1$

This implies that when the dataset is multiplied by k, the population standard deviation will be multiplied by the same factor:

i.e.

$New \sigma = k * \sigma$
