Please help I'm so confused pls

s = [(4-6)^2 + (7-6)^2 + (4-6)^2 + (10-6)^2 + (5-6)^2] / 5

Step-by-step explanation:

Given the data:

Number of miles biked each day:

X = 4, 7, 4, 10, 5

The mean of data :

Mean(m) = (sum of X) / n

Where n is the number of observations or days

m = (4 + 7 + 4 + 10 +5) / 5

m = 30 / 5

m = 6

The variance of the data (s):

s = [Sum of (x - m)^2] / n

s = [(4-6)^2 + (7-6)^2 + (4-6)^2 + (10-6)^2 + (5-6)^2] / 5

Where s = variance, m = mean, x = data values
