For this question, you are required to find the standard deviation for a set of data. The answer alone will not achieve full marks. There are many tools available to calculate the standard deviation. Here you are required to use several of the tools and show your working out to earn the marks. The data is the test results of 21 students who sat a mathematics quiz worth 100 marks. Results: 60, 47, 17, 43, 30, 90, 77, 61, 54,...

Calculate the sample standard deviation for this data set: 58,60, 74
Calculate the sample standard deviation for this data set: 58,60, 74. The formula for the sample standard deviation is shown, where n represents the sample size, x represents each value in the data set, and x represents the sample mean.\(s=\sqrt{\frac{\sum(x-\bar{x})^{2}}{n-1}}\)Step 1. Calculate the sample mean. Step 2. Calculate the deviations and the squares of the deviations. Step 3. Calculate the sample variance and the sample standard deviation. Provide your sample standard deviation answer precise to oñe decimal place

13. Below are the range and standard deviation for a set of
data. Use the range rule of thumb and compare it to the standard
deviation listed below. Does the range rule of thumb produce an
acceptable approximation? Suppose a researcher deems the
approximation as acceptable if it has an error less than 15%.
The estimated standard deviation is
Is this an acceptableapproximation?
A:.No, because the error of the range rule of thumb's
approximation is
greater than 15%.
B.Yes, because...
