Five years ago, 45% of registered voters were in favor of Medicare For All, 35% were opposed, and 20% were unsure. This year, a survey of 501 randomly selected registered voters showed that 235 were in favor, 201 were opposed, and 65 were unsure. At the 0.05 level of significance, test the claim that the proportions for all voters have stayed the same as they were 5 years ago.
