A data set contains the following values: 11, 3, 5, 18, 1, 4, 7. Find the population variance. Round your answer to 4 decimal places.

A data set contains the following six values. 10, 18, 13, 30, 23, 18 (Round the intermediate values to 3 decimal places. Round your final answers to 3 decimal places) Find the population standard deviation. Blank 1 Find the population variance. Blank 2

A population consist of multiple of five numbers where is 5, 10, 15, 20, 25, and 30 with sample size of 2. Find the population variance.

Given sample data:x -1 0 1 4f 1 1 3 1The range is ;The sample variance is ;The sample standard deviation is .Round to two decimals.

For the data set 6, 5, 10, 11, 13, the mean, x, is 9. What is the standard deviation?The formula for the sample standard deviation is 𝑠=1𝑛−1Σ(𝑥−𝑥ˉ)2s= n−11​ Σ(x− xˉ ) 2 ​ .Use the table to help you.Round your answer to the nearest tenth.

The mean and sample standard deviation of the dataset consisting of 9 observations is 14 and 10 respectively. Later it is noted that one observation 11 is wrongly noted as 6. What is the sample variance of the original dataset? (Correct to 2 decimal place accuracy)
