I need help with these 3 questions please:

Calculate the sample standard deviation for this data set: 88, 73, 91. The formula for the sample standard deviation is shown, where n represents the sample size, x represents each value in the data set, and i represents the sample mean.

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 one decimal place. square of deviation of 73 = square of deviation of 91 = sample standard deviation = Using the sum of squares formula (also known as the shortcut formula) for sample standard deviation, calculate the standard deviation of the numbers 17, 27, and 22. In the sum of squares formula, x represents the data value and n represents the number of values. standard deviation = Step 1. Determine the sum of squares of the three values. Step 2. Determine the square of the sum of the three values. (2% [:1 Step 3. Divide the result in Step 2 by n. Step 4. Subtract the result in Step 3 from the result in Step 1. Step 5.
