a 1. In 1995, the USDA commissioned a study of women's nutrition. Nutrient intake was measured for a random sample of 402 women aged 25-50 years. One of the questions of interest is whether women meet the federal nutritional intake guidelines. The table below shows the average recommended daily intake, the sample means and variances for iron and protein: Variable Recommended intalte Sample mean 11g Sample variance 30 Iron 15E 605 609 Protein 1000 2. The sample data also showed that the covariance between protein iron and protein is a hundred. Is there significant evidence at the 1% level that on average, woman fail to meet the federal guidelines? (20)
