Please help me with this problem I been stuck in this problem for 45 min and don't know how to go about it ????

9. According to Census data, in 1950, the population of the U.S. was 151.3 million, and 13.4% were living in the West. In 2021, the population was 332 million, and 23.9% were living in the West. Is the difference in percentages practically significant? Statistically significant? Or do these questions make sense? Explain in detail
