According to a 2018 study in the journal of nutrition, 81% of people who ate plant-based food for six months lowered their LDL (bad cholesterol) by an average of 22.5 points.

The majority of the others who kept the same meat-based diet did worse with cholesterol levels after six months of monitoring. I surveyed 150 of my co-workers.

96 of them said they would be willing to change their diet to plant-based only for 6 months.

Based on the sample, at the 5% significance level, what can be said about the claim?
