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 ko:hia 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 selecteikochia plants were resistant to glyphosate. Do the data provide convincing statistical evidence, at the leve of 0.05, that there has been an increase in the proportion of all kochia plants that are resistant to glyphosale?
