Question

What are the mean, variance, and standard deviation of these values? Round to the nearest tenth.

(PICTURE BELOW)

Answer 1

\[sd=\sqrt{\frac{ \sum_{}(x-\mu)^{2} }{ n }}\]
sd=standard deviation
μ= x bar
n is how many you have in the x column n=5

standard deviation is the square root of variance so just square SD

mean is the sum of all x then divide by n

\[\mu=\sum_{}\frac{ x }{ n }^{}\] where μ is the mean also known as x bar
