What are the odd of rolling two number cubes and getting the sum of 7

1 answer:

8 0

Number of possible outcomes of one cube = 6
Number of possible outcomes of the other cube = 6 
Number of possible outcomes of two cubes = 6 x 6 = 36 

Number of ways to roll a sum of 7 with two cubes = 6 

1 - 6 
2 - 5 
3 - 4 
4 - 3 
5 - 2 
6 - 1

In variables estimation sampling, the sample standard deviation is used to calculate the?

Nikitich [7]

The sample standard deviation is used to calculate the determine the spread of estimates for a set of observations (i.e., a data set) from the mean (average or expected value).

<h3>What is sample standard deviation?</h3>

The spread of a data distribution is measured by standard deviation. The average distance between each data point and the mean is measured.

The sample standard deviation (s) is a measurement of the variation from the expected values and is equal to the sample variance's square root.

where

s = sample standard deviation

N = the number of observations

$xi$ = the observed values of a sample item
