A biologist records the weights in grams of two species of birds.
Species X$:15.2,15.5,15.1,15.3,15.4$
Species Y$:14.8,15.0,15.2,14.9,15.1$
Construct a $95$ percent confidence interval estimate for the variance of each species' weights. Is there evidence of a difference in variation between the two species?

Species X: $(0.00897,0.3066){\text{ g}}^2$

Species Y: $(0.00897,0.3066){\text{ g}}^2$

There is no statistical evidence that the variability in weights differs between Species X and Y.

Species X: $(0.00897,0.2066){\text{ g}}^2$

Species Y: $(0.00797,0.2066){\text{ g}}^2$

There is statistical evidence that the variability in weights differs between Species X and Y.
