1. First,  find the mean: 87.2

2. We find the distance from each data point to the mean, 

First point: 83- square distance from mean- 17.64

85-87.2-4.84

82 - 87.2 -27.04

93-87.2 squared-33.64

83-87.2- 17.64

84-87.2-10.24

95-87.2-60.84

87-87.2-0.04

86-87.2-1.44

94-87.2- 46.24

Now, add everything up: 201.96

10 data points, so 201.96/10=20.196

Take the square root of that to get:\(\sqrt{20.196}=4.49..\)

So, 4.6?
