Are the economies that became member states of the European Union after 2004 catching up to the older members? The file EUGDP2017 contains real GDP growth rates in 2017 for the 28 EU countries, along with their status according to the date on which they became EU members (old - before 2004, new - 2004 and after).

a. Is there evidence of a difference in the median real GDP growth rates in 2017 between old and new member states? (Use \(\alpha=0.05\).)

b. What assumptions must you make in (a)?

c. Compare the results of (a) with those of Problem 10.9 (a).

Problem 10.9 (a).

Are the economies that became member states of the European Union after 2004 catching up to the older members? The file EUGDP2017 contains real GDP growth rates in 2017 for the 28EU$28EU$ countries, along with their status according to the date on which they became EU members (old - before 2004, new - 2004 and after)

a. Assuming that the population variances from both types of members are equal, is there an evidence of a difference in the mean growth rates? (Use α=0.05.)
