Tumbleweed, commonly found in the western United States, is the dried structure of certain plants that are blown by the wind. Kochia, a type of plant that turns into tumbleweed at the end of the summer, is a problem for farmers because it takes nutrients away from soil that would otherwise go to more beneficial plants. Scientists are concerned that kochia plants are becoming resistant to the most commonly used herbicide, glyphosate. In 2014, 19. 7 percent of 61 randomly selected kochia plants were resistant to glyphosate. In 2017, 38. 5 percent of 52 randomly selected kochia plants were resistant to glyphosate. You will conduct a significance test to determine if the data provides convincing statistical evidence, at the level of a = 0. 05, that there has been an increase in the proportion of all kochia plants that are resistant to glyphosate?
