A new procedure mixing Calcium hydroxide and Calcium silicate hydride nanotubes with concrete has been developed, and the strengths of various concrete specimens have been measured based on the relative proportion of calcium hydroxide and calcium silicate hydride tubes. 3 treatments are shown in the table below, 100% calcium hydroxide, 50% Calcium Hydroxide and 50% Calcium silicate hydride, and 100% calcium silicate hydride, all added as ~ 1% of the mixture to the concrete . Eight samples of each were used to produce the means and variances. A) Run ANOVA on this data to see if there are any differences  B) Why might classical ANOVA be inappropriate for this data set?

Question

A new procedure mixing Calcium hydroxide and Calcium silicate hydride nanotubes with
concrete has been developed, and the strengths of various concrete specimens have been measured
based on the relative proportion of calcium hydroxide and calcium silicate hydride tubes.
3 treatments are shown in the table below, 100% calcium hydroxide, 50% Calcium Hydroxide and 50%
Calcium silicate hydride, and 100% calcium silicate hydride, all added as ~ 1% of the mixture to the
concrete . Eight samples of each were used to produce the means and variances.

A) Run ANOVA on this data to see if there are any differences 
B) Why might classical ANOVA be inappropriate for this data set?
