How can we interpret standard deviation using the Empirical Rule?

1 answer:

3 0

Answer:The empirical rule notes that almost all of the data would fall within three standard deviations of the mean for a normal distribution. The empirical rule can be broken down into three parts: within the first standard deviation from the mean, 68 percent of data drop. Two standard deviations account for 95 percent.

Which of the following is NOT a solution to the inequality below? 4x+9>63

Sedbober [7]

Answer:

A. 13

Step-by-step explanation:

When you plug the numbers in, 4 times 13 = 52+9=61 and 63 is still greate so anything above 13 would make the sentence correct. So that is why 13 is NOT a solution.

The following data give the hourly wage rates (in dollars) of eight employees of a company 23 23 23 23 23 23 23 23 on Calculate

cupoosta [38]

Answer:

0 because they are the same

Step-by-step explanation:

The average of this the hourly wage is

μ = (23 + 23 + 23 + 23 + 23 + 23 + 23 + 23)/8 = 23

The standard deviation would then be

$\sigma = \sqrt{\frac{\Sum (x - \mu)^2}{n}} = \sqrt{\frac{(23 - 23)^2 + (23 - 23)^2 + ... + (23-23)^2}{8}} = \sqrt{\frac{0}{8}} = 0$

The value is indeed 0 because all the hourly wages are the same (23) and there's no deviation from the average
