8. Research Question: A nutritionist claims that the mean daily consumption of fiber for 20-39-year-old males is less than 20 grams per day. (The National Cancer Institute recommends that individuals consume 20-30 grams of fiber per day) In a survey of 457 males who were 20-39 years old, conducted by the U.S. Department of Agriculture, it was found that the mean daily intake of fiber was 19.1 grams, with standard deviation of 9.1 grams. Decide whether there is enough evidence to support the nutritionist’s claim at α=.05. If you lower the level of significance to α=.01 does your decision change. Explain.
