Consider the following sample data set: 34, 41, 23, 22, 23, 42, 24, 24, 69, 36. What is the standard deviation?

dybincka [34]

Answer:

standard deviation comes out to be equal to 14.63

Step-by-step explanation:

given numbers,

34, 41, 23, 22, 23, 42, 24, 24, 69, 36

arranging in ascending order

22, 23, 23, 24, 24, 34. 36, 41, 42, 69

mean = $\dfrac{22+23+23+24+24+34+36+41+42+69}{10}$

= 33.8

standard deviation = $\sqrt{\frac{\sum (x-\bar{x})^2}{n-1}}$

= $\sqrt{\frac{1927.6}{10-1}}$

= 14.63

hence, the standard deviation comes out to be equal to 14.63

What are all the factos of 36

oksano4ka [1.4K]

Hi there!

»»————-　★　————-««

I believe your answer is:

{1, 2, 3, 4, 6, 9, 12, 18, 36}

»»————-　★　————-««

Here’s why:

A factor is a whole number that is multiplied by another to have a product have another number.

⸻⸻⸻⸻

The Factors Are:

1 (1 * 36 = 36)
2 (2 * 18 = 36)
3 (3 * 12 = 36)
4 (4 * 9 = 36)
6 (6 * 6 = 36)
9 (9 * 4 = 36)
12 (12 * 3 = 36)
18 (18 * 2 = 36)
36 (36 * 1 = 36)

⸻⸻⸻⸻
