In a survey taken in 2019, 20 out of 50 women and 17 out of 45 men said they felt that our country was headed in the wrong direction regarding universal healthcare.

Do these data provide sufficient evidence at the 0.01 level of significance to conclude that the proportions of women and men that feel our country is headed in the wrong direction regarding healthcare are equal?
