An MSCI survey showed that there continues to be a slow increase in the overall percentage of women on boards of directors globally. The study reported that 7 of 22 (32%) Austrian companies sampled, 86 of 103 (83%) French companies sampled, 40 of 92 (43%) German companies sampled, 5 of 31 (16%) Irish companies sampled, and 37 of 55 (67%) Italian companies sampled have at least three female directors on their boards. (Data extracted from MSCI, 2014 Survey of Women on Boards, bit.ly/1MMiET1.)

a. Is there evidence of a significant difference among the countries with respect to the proportion of companies who have at least three female directors on their boards? (Use a = 0.05).

b. Determine the p-value and interpret its meaning.

c. If appropriate, use the Marascuilo procedure and a = 0.05 to determine which countries differ.
