Fiona recorded the number of miles she biked each day last week as shown below. 4, 7, 4, 10, 5 The mean is given by m = 6. Which equation shows the variance for the number of miles Fiona biked last week?
Given that the mean of the equation is given by: m=6 the variance is given by the formula: [∑(x-m)²]/(n-1) ∑(x-m)²=[(4-6)²+(7-6)²+(4-6)²+(10-6)²+(5-6)²]=26 hence the expression will be: 26/(n-1) where n=5, the number of times she ran
