The variance of a sample of 144 observations equals 576. the standard deviation of the sample equals?
1 answer:
When the variance of a sample of 144 observation is 576 then, the standard deviation of the sample equals 24
The variance is a measure of variability. It is calculated by taking the average of squared deviations from the mean. Variance tells you the degree of spread in your data set
Standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.
Given,
The number of samples = 144
The variance = 576
The standard deviation is the square root of variance
The standard deviation = =24
Hence, when the variance of a sample of 144 observation is 576 then, the standard deviation of the sample equals 24

Answer:
11, 13,15 8, 11, 14 op = 2,3
16, 12, 8 17. 14, 11 op = -4,-3
3, 7, 15 24, 16. 12 op 4,4 because difference = op 4, 8 = 4 op -8, -4 = 4
Step-by-step explanation:
9+ 2 = 11, 13,15 ordered pair 2
5+ 3 = 8, 11, 14 ordered pair 3
20-4 = 16, 12, 8 ordered pair -4
20-3 = 17. 14, 11 ordered pair -3
1 x 2 +1 = 3, 7, 15 ordered pair 4, 8 = 4
40 / 2 + 4 = 24, 16. 12 ordered pair -8, -4 = 4
the reason why the value is not an integer, is most likely because the 21.2<span>° is just an approximation.</span>
