Answer:
To find the mean, you have to add all numbers together and divide them by the number of data points.
let me show what I mean:
The heights of the dogs are 600,470,170, 430,300.
Step-by-step explanation:
600+470+170+430+300.
1970.
Now we have to divide 1,970 by 5 ( because we are given 5 data points)
The mean is:
1970/5=394
Variance: First, arrange the data from least to greatest.
s2 = 27130
Standard Deviation: 164.71187
