A meteorologist is studying the monthly rainfall in a section of the Brazilian rainforest. She recorded the monthly rainfall, in inches, for last year. They were:
1.8, 2.5, 2.6, 4.4, 4.4, 7.3, 8.0, 9.5, 10.3, 10.4, 11.1, 11.7
For this data set:
Mu = 7, N = 12. Sigma squared = StartFraction (x 1 minus mu) Squared + (x 2 minus mu) squared + ellipsis + (x N minus mu) squared Over N EndFraction. Sigma squared = StartFraction (1.8 minus 7) squared + (2.5 minus 7) squared + ellipsis + (11.7 minus 7) squared Over 12 EndFraction
Fill in the missing values in the formula. What is the variance?
