For the dataset {26, 30, 34, 38, 42, 46, 50}:
n = 7
Σx = 266
Σx² = 10556
µ = 1/n Σx
σ = √(1/n Σ(x - µ)²) = √(1/n Σx² - (1/n Σx)²)
→ σ = √(1/7 × 10556 - (266/7)²) = √(1508 - 38²) = √64 = 8.

What percentage of the data falls outside 1 standard deviation of the mean?
One standard deviation for one side will be 34% of data. So within 1 std. dev. to both sides will be 68% (approximately) .the data falls outside 1 standard deviation of the mean will be 1.00 - 0.68 = 0.32 (32 %)
What is the range of 32 24 34 30 28 28 26 36 26?

Are normally distributed with a mean of 68 inches and a standard deviation of 2 inches What is the probability that the height of a randomly selected female college basketball player is more than 66?
84% To solve this problem, you must first realize that 66 inches is one standard deviation below the mean. The empirical rule states that 34% will be between the mean and 1 standard deviation below the mean. We are looking for the prob. of the height being greater than 66 inches, which is then 50% (for the entire right side of the distribution) + 34%

30 is.
Data A 77 64 71 55 72 73 71 47 52 Data 40 25 26 12 2 46 22 23 28 34 which one what data sets shows more variatiion around the mean?
Compute the variance (or its square root , standard deviation) of each of the data set. Set 1: standard deviation = 10.121 Set 2: standard deviation = 12.09 Set 2 shows more variation around the mean. Check the link below

What is the point estimate for the standard deviation of the population A simple random sample of 8 employees 1 2 3 4 5 6 7 8 age 25 32 26 40 50 54 22 23 gender m m m m f m m f?
how do you find point estimate for standard deviation?1) The dashes are only here to keep the chart lined up. I posted this before and it didnt line up correctly.2) Hopefully you're familiar with X bar. The three Xs have the bar (_) symbol above them. Hope this helps!Make Chart First=-----------------------(_)---------------(_)--------------(_)--------xi--------------x------------ (xi-x)------------(xi-x)2-------25-------------34--------------(-9)---------------81-------32-------------34--------------(-2)----------------4-------26-------------34--------------(-8)---------------64-------40-------------34---------------6-----------------36-------50-------------34--------------16---------------256-------54-------------34--------------20----------------400-------22-------------34-------------(-12)--------------144-------23-------------34-------------(-11)-------------121Total= 272--------------------Total= 0----- Total= 1106Point estimate standard deviation of population :The square root of:*1106/ 8-1=1106/7=The square root of 158= 12.56980508997653471* I do not know how to show the square root on here but for the equation the number of sample is variable n. For the bottom of the division problem it is (n-1), which makes it 8-1=7So the point estimate standard deviation of population is 12.56980508997653471
